I'm having the same issues as you with 2 exceptions: I don't have any
fanart in my setup, mainly because I haven't bothered to look into what
I need to do to implement it. Also, I've noticed that when I'm looking
at things in Mythweb, there's a 10-15 second gap in looking at those
descriptions on a recording or listing. If you go to the listings page
and put your cursor over a show, I get a box in the lower left in green
saying "1 request pending". After about 10-15 seconds, the description
finally pops up. It does this in "Upcoming Recordings" too, but the
"Backend Status" seems OK with their popups. Moving around in MythWeb
seems slower too but nothing too major.
I can provide logs and other details as well. Anything to help.
