Recently, one of our customers approached us with the same error message. Now, let’s see how our Support Engineers resolve this error for our customers.

Initially, we checked the apache error logs from the path /usr/local/apache/logs/error_log. Here we found the issue to be with the mod_rewrite.

After that, we ran the below command

httpd -V

As a result, we found the Apache configuration file to be /etc/httpd/conf/httpd.conf.

Then in the Apache configuration file, we removed the comment in the below line.

LoadModule rewrite_module modules/mod_rewrite.so

This immediately fixed the issue.

In another case, we added the below code into the .htaccess file to fix the HTTP 500 error.

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/$1 [L]
