    I check where the problem occurs and what files, modules, or settings may be involved.

    03

    We agree on a solution

    I explain what needs to be done, what options are available, and how long it may take.

    04

    I complete the work

    I make the changes, test the result, and show the finished solution.

    Quick problem-solving

    Technical errors are like holes through which your budget quietly leaks away

    Freezes, broken buttons, or “poor” layout can destroy a customer’s trust in a matter of seconds. I don’t just fix the code—I resolve the technical issues that prevent your customers from easily placing an order.

    More sales

    I'm fixing the logic behind the shopping cart, checkout, and payment gateways. I'm making sure that the user can move seamlessly from clicking “Buy” to the “Thank you for your order” page.

    A high-quality mobile version

    A large portion of the traffic comes from smartphones. I’m fixing the responsive design bugs: elements that extend beyond the screen, clunky filters, and pop-ups that cover the content and won’t close.

    SEO audit

    I fix errors that are invisible to the naked eye but cause Google to penalize your site: 404 pages, infinite redirect loops, duplicate content, and microdata conflicts.

    Faster performance

    Heavy scripts and module conflicts cause pages to take forever to load. I identify and optimize the code that’s slowing down the site.

      Answers to questions

      Frequently asked questions

      What actually causes an opencart 500 error?

      It's a generic server failure: PHP hit something it can't handle and shows a blank page or a 500 code instead of the site. Dozens of things can trigger it, from a corrupted file to a module conflict, so the code alone doesn't tell you the cause. You need to check the logs.

      I'm getting an opencart internal server error right after installing a new module. Is that the cause?

      Probably, since the timing lines up. But sometimes it's not the module itself, it's a conflict with something already installed or with the theme. I check the server logs and compare what changed right before it broke.

      My store shows an opencart white screen and nothing else. How long does that take to fix?

      Depends on the cause. If it's one fatal error in the code, usually fast. If the site crashed because of a database issue or a bad update, it can take longer. I'll give you a real estimate once I've seen the logs.

      OpenCart not working properly, but there's no error message at all. Where do you even start?

      With the server logs and slow SQL queries. No error usually means the script is running, just very slowly: heavy database queries or an infinite loop in a module's code are the usual suspects.

      I get opencart cannot login admin no matter what I try. What are my options?

      I can reset the admin password directly through the database, that part is quick. While I'm in there, I'll also check whether something else is blocking access, like a server rule or a broken session.

      Can you reset admin password without breaking anything else?

      Yes, opencart reset admin password is a safe, contained fix on its own. I just make sure I'm not touching anything that could affect other admin accounts or permissions while I'm at it.

      Orders come through, then vanish from the admin panel. What's going on?

      Sounds like an opencart order not saving properly, and that usually points to the database, a write error, or a payment module conflict. I check the logs and the order table to see exactly where it drops.

      Opencart emails not sending to customers after checkout. Is that OpenCart or my hosting?

      Could be either. Sometimes it's the SMTP settings, sometimes the mail server flags it as spam, sometimes it's a bug in the code that sends it. I check both the logs and the settings to find the real cause.

      My store is opencart broken after update, and I don't know where to start. Can that actually be fixed?

      Yes, and it happens more often than you'd think. Usually it's not the update itself, it's an old module or custom code that isn't compatible with the new version. I find what's conflicting and fix it without rolling back the whole project.

      I'm worried about an opencart hack. How do I know for sure?

      I look for the usual signs: unfamiliar code in the files, admin accounts you didn't create, strange redirects, or spam pages that showed up out of nowhere. If it's confirmed, I clean the files and close whatever let them in.

      How to clear opencart cache if the site keeps showing an old version after edits?

      You can clear it through the admin panel, or manually through the files on the server if you can't get into the panel at all. Usually that's quick, but if clearing it doesn't help, the problem is somewhere else.

      I'm getting an opencart database error and have no idea what to do with it.

      That usually shows up after a hosting move, an update, or a server hiccup. I check the connection, the config file, and the database itself, the cause is almost always in one of those three places.

      Can you fix a bug without me explaining exactly what's wrong technically?

      Yes, that's normal. Send a link and describe what you're seeing in plain words, and I'll figure out the technical side myself.

      Do you only take on full projects, or can I get a quick opencart bug fix?

      Quick fixes are most of what I do. Send the link and a description, and I'll tell you what I found and how long that specific fix will take.

      Troubleshooting website issues on opencart

      If your store shows a white screen, customers can’t check out, the layout breaks on mobile, or installed modules are fighting each other, that’s what I fix. I find the actual cause in the code and resolve it, so the store stays stable and doesn’t lose customers over something that should never have happened in the first place.

      Errors rarely show up for no reason. There’s usually a specific trigger: a fresh module, an update, a hosting change, wrong file permissions, or an outdated PHP version. My job isn’t to guess, it’s to find that exact trigger and fix it, not just patch the symptom.

      The errors people usually come to me with

      • Server errors. Opencart http error 500, opencart error 500, opencart 500 internal server error, opencart 502 bad gateway — different names for the same problem: the server couldn’t return the page. Causes range from a broken file to the server running out of memory.
      • Notice and warning messages. An opencart warning error or opencart notice error doesn’t always break the site outright, but it clutters the logs and makes it harder to spot the real problem when something actually goes wrong.
      • The site won’t load or freezes. A white screen, an endless spinner, a connection error — in any of these cases, I start with the server logs, not random guessing.
      • Admin access problems. Opencart cannot access admin, can’t log in, a forgotten password, or opencart admin not working at all — sometimes it looks like opencart white screen admin instead of the dashboard. Usually it’s file permissions, a stale cache, or a conflict after an update.
      • Parts of the storefront stop working. Search stops returning results, filters do nothing, or a specific extension just stops working — usually a JavaScript conflict between modules or the theme.
      • Orders and email problems. Orders vanishing after checkout, confirmation emails never arriving — two different issues that look similar but get fixed differently.
      • Files and cache. An opencart file size error usually means the server’s upload limit is smaller than what the store expects, and it’s an easy setting to fix. Opencart cache clear or opencart clear cache sometimes fixes things instantly, and sometimes it’s just hiding the real issue for a while.
      • Database issues. An opencart database connection error usually shows up after a hosting move or a server hiccup, and the fix is in the configuration, not just the database itself.
      • After updates. “It broke right after I updated” is the most common way people describe this. Usually the update isn’t the real problem, it’s an old module or custom code that isn’t compatible with the new version.
      • Security. Opencart vulnerabilities and a hack are their own category: closing the hole matters, checking that no software got left behind matters too, and so does deleting anything that shouldn’t be there.

      How opencart troubleshooting actually works

      Opencart bug fixing and opencart errors fix work doesn’t start with changes, it starts with a diagnosis: server logs, browser console, comparing what changed right before things broke. Once the cause is clear, I make the fix, that way the same problem doesn’t resurface somewhere else next week.

      Clearing the cache is often the first thing worth trying, and sometimes that’s genuinely all it takes. But if clearing it doesn’t change anything, the real issue is deeper, and I move on to the code, the database, or the server settings.

      Mobile layout and checkout

      A broken mobile layout isn’t a minor detail. Most shoppers come from a phone, and a clunky interface there costs you orders just as surely as the site being fully down would. I find the exact element that’s overflowing the screen or blocking content and fix that spot, not redesign the whole thing.

      Cart logic, checkout, registration, and payment gateways are what directly affect sales. The path from clicking “Buy” to the “Thank you for your order” page should be smooth, and if a customer drops off somewhere along that path, I find exactly where.

      How the work goes

      1. You describe the task. A link to the site, a screenshot of the error, or a short description is enough to start.
      2. I analyze the site. I check where the problem occurs on the page and which files, modules, or settings are involved.
      3. We agree on a solution. I explain what needs to be done, what the options are, and how long it may take.
      4. I do the work. I make the changes, test the result, and show you the finished fix.

      I usually reply within 10–20 minutes.

      Pricing

      Cost depends on what actually broke: one code-level bug fix is quicker than recovering from a hack or untangling a conflict between a dozen active modules and features you may not even use. I give you a real number after I’ve looked at the logs and the code, not before.
