I've noticed this too, but can't really find the cause of this. I suspect it's some missing files, but I don't have full access to the forum software it's full releases anymore as my license for updates expired. I won't renew this until they release IPB4, so this might hang on for a while, but I'm searching if I can fix it another way.... You might also try the "Change Theme" option below and set it to the default.

This might speed it up.
