How to Fix 500 Internal Server Error?

Before you make any changes, it is necessary to enable Developer Mode. It will allow you to debug Magento and see all detailed exceptions on your error page. 

For Magento 2, you can enable Developer Mode by running the following command line:

bin/magento deploy:mode:set developer

Now lets explore some ways to fix internal 500 server error. 

Change Magento File Permission

Permission error is one of the most common errors in 500 internal server error. This happens when you log into the admin panel. To fix this error, you need to change Magento file permissions of index.php file from root 664 to 644.

Now, run the following commands one by one. This way, the issue can be resolved.

cd <your Magento install dir>
find . -type f -exec chmod 644 {} \; // 644 permission for files
find . -type d -exec chmod 755 {} \; // 755 permission for directory
chown -R :<web server group> .
chmod u+x bin/magento

Increase Php_value Memory_limit

At times, memory limit can occur on a specific page of your web store, like checkout page or product page. It is also a vital issue in Magento 500 server error. We suggest that you should have at least 256M for php_memory_limit value if your store has nearly 500 products. There is no difficulty in checking the problem via the .htaccess file or php.ini file.

If you need to increase the volume, add the following lines for php.ini file:

memory_limit = 256M

Otherwise, for .htaccess file,please add the following lines:

<IfModule mod_php5.c>
php_value memory_limit 256M
</IfModule>

It can not be done by yourself because of the lack of permission on hosting. Hence, you will need the support from hosting provider.

Resolve Third Party Plugin Issue

Third party plugin issue can be a very common error that you may encounter once you install or update a plugin for your Magento store. It is basically a conflict which occurs between new plugin and older plugins available on your store. If that happens, run the below command to turn off the mod.

php bin/magento mod:disable
