A server error means there is either a problem with the operating system, the website or the Internet connection. There are many different kinds of internal server errors, but a "500 error" is the most common. It is up to the operators of the Web server site to locate and analyse the logs which should give further information about the error.
Internal Server Error messages indicate that something, in general, is wrong.
A Permissions Error
A PHP Timeout
A Coding Error in .htaccess
Check the log to find the exact reason for Internal Server Error and resolve accordingly.1) Take a look at your server log to take note of the content of this log file.
2) Do the action that triggers the 500 error
3) Now check the server log again for the additional content that went in there for this error. That will tell you what is going on and why the server gave this error.
It’s important to note that the server side of an application generates this error even though you may see the error code inside your browser. That means that your HTML, client-side JavaScript, or anything else that runs in a browser is not the source of a 500 Internal Server Error. Of course, the name does imply that it’s a server error, but systems have grown so complex today, that this reminder could be helpful.

How to do in detail?
CHECK THE ERROR LOGS!
With any error message, particularly one as broad as the 500 Internal Server Error, you will first want to check any Apache and PHP error logs for your server. These logs can provide valuable context related to any code failures or other potential causes of a site failure.
ERROR WITH AN .HTACCESS FILE
If you are using a .htaccess on your site, it may be interfering with the web page you are trying to load into your browser. Please double check the .htaccess configuration. Any syntax errors will cause a 500 Internal Server Error message to be displayed instead of your website.
To confirm whether a misconfiguration .htaccess is the cause of the 500 Internal Server error, either remove or rename the .htaccess file temporarily and then try to reload the page
PHP CODING TIMING OUT
If your PHP script makes external network connections, the connections may time out. If too many connections are attempted and time out, this will cause a "500 Internal Server Error." To prevent these time outs and errors, you'll want to make sure that PHP scripts be coded with some timeout rules. Typically, however, catching a timeout error when connecting to a database or externally to remote resources (example: RSS feeds) are difficult. They, in effect, freeze the script from continuing to run.
Removing any external connections can increase both the performance of your website and decrease the chances of you receiving a "500 Internal Server Error."
