System Configuration http error 500

[The_Paperplace]

Hi,

I'm trying to access to the configuration section of my dashboard but doesn't allow me and I receive an HTTP ERROR 500. I didn't do any specific changes in the website if not refreshing cache or reindexing. Could someone help me please?

Thanks.

The 500 Internal Server Error is a very general HTTP status code that means something has gone wrong on the web site's server, but the server could not be more specific on what the exact problem is.

Check the following to diagnose the issue: 

• A Permissions Error. In most cases, a 500 Internal Server Error is due to an incorrect permission on one or more files or folders. In most of those cases, an incorrect permission on a PHP and CGI script is to blame. These should usually be set at 0775 (-rwxr-xr-x).
• A PHP Timeout. If your script connects to external resources and those resources timeout, an HTTP 500 error can occur. Timeout rules, or better error handling in your script, should help if this is the cause of the 500 error.
• A Coding Error in .htaccess. While not as common, be sure to check that your site's .htaccess file is properly structured

Hi @The_Paperplace

Did you see any error message logged in the system.log or exception.log file under var/log directory of your Magento installation?

Check your .htaccess file and make sure your IP Address didn't get accidentally blocked there. That has happened to me in the past.
