I am getting the following type of error message on both admin and frontend of my WordPress website.
Internal Server Error
The server encountered an internal error or misconfiguration and was
unable to complete your request. Please contact the server
administrator to inform of the time the error occurred and of anything
you might have done that may have caused the error.More information about this error may be available in the server error
log.
I already tried to rename the plugin directory, removed or renamed the .htaccess file and changed WordPress file permissions to 755. But no luck.
I have the exactly same problem on my WP site, because I reached the limit of my godaddy web hosting resources. They say I need to buy more server resources for my website to work regularly.
