500 Internal Server Error for Shared Web Hosting

I receive the following error, the hosting company indicates that other server websites do not face the same problem. Does anyone know how to fix it?

Internal Server Error

The server encountered an internal error or misconfiguration and could not process your request.

Please contact the server administrator at the webmaster @ .net address to inform him of the time at which this error occurred and the actions you performed just before this mistake.

More information about this error may be available in the server error log.

In addition, a 500 Internal Server Error error occurred when attempting to use an ErrorDocument to handle the request.

The error logs of the server are as follows
