Slow website response

Well after last nights maintenance latest activity returns a server error and discussions takes ages to load. Once you get there though, individual threads boot up fast enough.🤔

I wouldn't say things were slow - if anything, I think it's got a bit faster since the enforced shut down. I'm using an iMac with the latest version of Monterey running and Chrome as the browser.

What I have experienced of late is that I can reply to a post, click the 'Reply' button and there's nothing there.  However, if I go back via 'Discussions' to that post, my entry is showing. Weird??
