I – What does it mean by Magento 2 Error 500? 


When you enter an exact URL into the address bar or click a link on a website, you request the server to show you a page. Presently, for some reason, the server can’t return the requested page and notifies you that you are facing an internal server error.

Magento internal server error 500 (Magento 500 error) is a general HTTP status code in which something has gone wrong with the site’s server, but the server could not identify what the exact issue is.

Sometimes, a 500 Internal Server Error may be temporary and will disappear when you refresh/reload the page. If it appears during the checkout process at an online store, don’t be surprised if duplicate attempts to checkout create several orders. Most online merchants have automatic protections against this behavior, but it’s still something to keep in mind.

It’s necessary to check the server error logs to get more information to understand a Magento internal server error 500. Foremost, you need to enable the Developer Mode, which allows you to debug Magento and see detailed exceptions on your error page, not just error messages such as: 

  • There has been an error processing your request
  • Magento exception printing is disabled by default for security reasons
  • Magento 500 Internal Server Error

For Magento 2 users, the Developer Mode will be enabled when you run the following command line in the Magento bootstrap file: 

php bin/magento deploy:mode:set developer

II – The Causes of Magento Internal Server Error 500 

There can be many reasons behind this error. However, a 500 error in Magento 2 can originate from one of these five most common reasons: 

  • Permission issues 
  • Memory limitation 
  • Issues in the .htaccess file 
  • Missing modules
  • Third-party plugin issues

Permission issues 

One of the most common reasons causing Magento 2 error 500 is the misconfigured permissions of the Magento files. People usually face this error while accessing the Magento admin panel or the Magento connect manager. This is because the default permission of the index files after Magento installation will be 664. Some systems won’t accept these permissions and then show this error. 

Memory limitation 

The PHP memory limitation is another common reason that may result in a Magento internal server error 500 after upgrading the data.  Magento is a resource-wasting application, and this error can arise when the server or the user’s account does not provide enough resources to run Magento. 

For example, insufficient memory or low execution time set for the account can often generate problems. Usually, most web hosts set the default memory limit as 20MB, 32MB, 64MB, etc. 

However, it’s not the same in Magento websites. So, a sensible memory allocation is 256MB. Similarly, the default timeout value may be 30sec, 60sec, 90sec, etc. Sometimes, the Magento application takes longer to return the output and ends up with this error.

Issues in the .htaccess file 

Issues in the .htaccess file commonly occur when you try to install some components such as themes, plugins, patches, etc., in Magento. Wrong configurations in the .htaccess file can block the installation of new components. For instance, syntax errors, URL rewrite errors, or typo errors in .htaccess can cause problems.

Missing modules 

Sometimes you may receive Magento 500 errors during Magento installation because the server doesn’t support specific criteria.

Third-party plugin issue 

You can also get the Magento internal server error after installing new plugins or performing upgrades.


III – How to Fix Magento 2 Error 500? 


Does 500 Error significantly impact your website? 

First of all, the error surely affects the user experience slightly or significantly. It does matter if it disappears right after users reload the page. If not, your online store is likely to lose potential customers and rarely turn back to shopping because of such a bad experience.  

On the other hand, a Magento 2 error 500 can negatively hurt your website’s ranking if it persists for hours. 

For each reason leading to a Magento 2 Error 500, there will be a relevant solution to fix it. 

Change Magento file permission

It’s common to see Magento 500 Internal Server Errors (Magento 500 error) when logging in to the admin panel. To fix it, access the file manager of your Magento website and adjust the permission of the index.php file in root from 664 to 644. 

You should also change the permission of another index.php file located in downloader/index.php to 644.

Increase php_value memory_limit 

Sometimes, the error may appear on a specific page of your websites like Checkout Page or Product Page when your server lacks the resources to run Magento. It’s recommended for a store with around 500 products to have at least 256M for php_memory_limit value. There’s no difficulty in checking this value via the .htaccess file or php.ini file. 

For the .htaccess file, add the following lines:

<IfModule mod_php5.c>
php_value memory_limit 256M

For the php.ini file, please add/change the following line:

memory_limit = 256M

Because of the lack of permission on hosting, you might not do it yourself, so ask for help from your hosting provider, or you can select a hosting from this list of best optimized Magento hosting to avoid a lack of resources. 

Rename/remove .htaccess file

If you suspect that issues in the .htaccess file caused the Magento 2 Error 500 on your website, try renaming the .htaccess file to check if the error is fixed. 

After that, check the error logs in /var/log/httpd or /var/log/apache2. If there are other issues arising, you must recover the configurations. 

Install missed modules 

You can use the default Magento Check ( to find out if there is any module missing to install them, and the issue will be fixed.

Get support from plugin developers 

If the problem happens because of third-party plugins, use the command “php bin/magento mod:disable” to turn off the mod and contact your plugin developer to ask for support.

This problem isn’t a big deal if you buy extensions from a reliable extension builder like BSS – the company that is named Adobe Bronze Solution Partner.
