I can't see any errors under Apache for today, this is the last entry:-
[Thu Mar 21 07:30:00.775293 2024] [access_compat:error] [pid 53001:tid 23407368332864] [client 79.124.59.74:58418] AH01797: client denied by server configuration: /home/coastguards/public_html/forum/uploads/javascript_global/index.php
The site was fine this morning, I am not aware of any changes.
I can see one change, php was updated from 8.1 to 8.2 globally. I changed back to 8.1 for this domain, now firefox shows:-
Service Unavailable
The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.
Additionally, a 503 Service Unavailable error was encountered while trying to use an ErrorDocument to handle the request.
... and after a few minutes and a cache clear, I'm back up - panic over!
Thanks for the assistance.
