How to detect a 500 error in my PrestaShop store?

This 500 error is basically the web server's way of saying "Oops!". We can't say more, but an error has occurred. This is called a server-side problem. This means that the hosting service hosting the website has gone down. This warning is very general and usually indicates issues with PHP configuration, programming, or website permissions. Most often, the bug is accompanied by a brief explanation, similar to this one. The server reported an unexpected error and could not complete the client request. It's important not to confuse it with the HTTP404: page not found error, which we've also covered in this blog. You can always check it at any time. This error can occur in any browser or operating system. So no, the new Apple Mac Pro will not prevent you from meeting her at one time or another...).

Solution to fix 500 PrestaShop errors.

.htaccess file

More than 80% of cases are due to the .htaccess file. Connect to FTP to correct the problem. Rename your .htaccess file to .htaccess.old

File permissions

You may get a 500 error if you touch the folders and files (CHMOD) right. Unfortunately, all hosts have different rights to folders and files. Here is an example for OVH (the French leader): The root of your site must be located in 705 (by default at OVH). Other directories should not exceed 755. PHP/cgi scripts should not exceed 755. Some hosting companies require you to grant "write access" (or do a CHMOD 755) to your files or folders to install PrestaShop. After installation, be sure to set your folders to 755 or 775, and your files to 644. Important: Permissions set to 777 cannot be secured.

Error 500 Prestashop Server response time exceeded.

As with all servers, your server has a maximum response time for running scripts. (Example: Import a CSV or generate images for the store). This prevents scripts from looping endlessly on the server. If the timeout is exceeded, a 500 error is displayed. To correct this, just increase this time (30 seconds by default), go to the PHP settings of your Plesk, Cpanel, ect... and modify the "max_execution_time" line, put the desired time in seconds (For 2 minutes, it should be noted: 120) which will affect the configuration of the php.ini file. For information, the max_execution_time parameter is used to determine the maximum execution time of a script in seconds. The default configuration is 30 seconds. For security reasons, be sure to reset to default after you complete your CSV import. Hackers will have an easier time hacking into your site if they have a longer query time. If you don't have this setting, you'll need to contact your host. If your server's mcrypt function is not enabled, Prestashop will receive a 500 error.

Error 500 due to outdated Prestashop modules

Regular PrestaShop updates are recommended to improve the security of your PrestaShop online store and allow you to access new features. It is important to remember that updates can cause bugs, including the 500 error. 500 errors are usually caused by outdated modules. You may find that some of your modules are not compatible with PrestaShop 1.5 or 1.7 and prevent you from seeing certain pages of your website. We recommend that you update all your modules if you encounter this type of problem. To find official modules compatible with your CMS version, visit the PrestaShop Add-ons Marketplace. A module setting error can also cause a 500 error. This problem is most often caused by incorrect module setting. To check if the bug is still present, go to the module folder and rename it.
