Hello Guys im having a problem about 500 Internal Server error.
Sometimes when i open or create threads i get this error.

But when i make shorter description it works.
But sometimes long descriptions work too.

Here's what on the Error Page:

Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, [email protected] and inform them of the time the error occurred, and anything you might have done that may have caused the error.

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

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

I installed Google Seo & Im using myBB 1.4.16 here's what on my htaccess:
