If you have recently done an upgrade of your joomla site and you now get this "Internal Server Error 500" you will find an answer just check this article for a possible solution of this problem on how to solve this annoying error.

A fresh Joomla Content Management System install includes a file called .htaccess, which you can see in the main folder or the root folder of your Joomla installation. This file contains certain joomla configuration settings, which may get in conflict with the current web server configuration. The result would be an Internal Server Error 500 displayed whenever you try to view your website.

You can determine whether it is the .htaccess file that is causes the error by renaming it to a .htaccess (disabling the file by renaming). Should this resolve the error, you would at least know where to look for the exact cause of the problem. It must be one of the directives within the .htaccess file, so it would only a matter of finding our which one it is and removing it (or commenting it).

1. Open the .htaccess file in your joomla root folder with a plain text editor - you can edit it via the File Manager on your web hosting control panel And find this line:
Options +FollowSymLinks

If you see it, put a # in front of it, so it would be look like this:

#Options +FollowSymLinks
putting # in Options +FollowSymLinks .htaccess file means you are commenting the Options +FollowSymLinks line in the .htaccess, And that's it. I hope this tutorial helps you.
