It can seem really annoying to find your own website down by server error 500. However, there are ways by which you can fix the problem and get your site up again. Here are some of the most effective troubleshooting techniques to apply.
Add-ons, third-party scripts, or software you have recently activated can interrupt your existing server settings. To determine if this is the case, deactivate or uninstall the add-ons individually. When you do it one at a time, you can determine the cause of the 500 error.
It is not difficult to do so with plugins if you own a WordPress website. simply navigate to your dashboard and select ‘Plugins’ followed by ‘Installed Plugins.’ After that, deactivate the first plugin and see if the error is still there. If the error gets fixed, you know that the plugin is causing the problem. Now, you should reactivate the prior plugin and repeat the whole process individually for all the plugins. It will allow you to instantly find out the exact cause of the error. You might also notice that less active plugins on your WordPress website actually enable it to run more seamlessly.
Apart from this, its also possible that your plugins or themes are incompatible with the new update. So, if you’ve upgraded your software, deactivate plugins or themes one at a time. Then find if the error disappears and which plugin or theme was the cause of it.
If you are familiar with the WordPress debugging process, try to install a plugin like WP Debugging. It will help you find the issue that your server is facing. This plugin sets certain debug constants in wp-config.php on plugin activation. It also eliminates them when you deactivate the plugin. This plugin thus allows you to identify precisely what the issue is with your website. So, it leads to a speedier fix.
If the HTTP Error 500 is associated with a PHP time out, you should think about creating error handling or time out rules in your script. You can go to this list of php.ini directives to correctly configure your PHP setup.
It may also be possible that wrong permissions on a folder or files that have a PHP or CGI script isn’t permitting the script to run. So, you should check your permissions and ensure that you set them properly on your server.
Wrong coding of your .htaccess file is another reason you may encounter an internal server error. If you are seeing this error, you can try to edit the file. The .htaccess files enable you to handle how long resources must be present in a browser’s cache.
To find your .htaccess file, use a file manager like cPanel to access your website files. The files will be there in the public_html directory. In most cases, the server, by default, hides the file from view. So, you must toggle hidden files on to view it.
If none of the measures work out for you, don’t worry. There’s another way to rectify server error 500. It is to see if the software you have recently installed or upgraded has actually upgraded or installed. You must refresh the software. For it, go to the website of the vendor and read the instructions.
If fixing software issues and debugging server-side scripts fails to resolve this error, you must ask your server administrator for help. Internal server error 500 can arise in various operating systems for a wide range of reasons. Ask your service provider to view your error logs and find out what is causing this issue.
If your website reporting 500 errors runs on Microsoft IIS, you might notice a more particular error message. Here is a list of these errors you can see.
