I have been trying to edit the pages of my website over the last few days and I have found it quite slow. This evening it was even more slow than before. I rebooted my laptop in case that was a problem and when I tried to log back in to my site's wp-admin I received this error:
Internal Server Error - Read
The server encountered an internal error or misconfiguration and was unable to complete your request.
I have tried several times and the Reference is different each time.
I can still view my website but it is very slow:
