In reply to Will_Armstrong:
I don't know if this is part of the same issue, but on UKH I just tried to add a complete ticklist to my Logbook in one go (by ticking every one of them individually - I can't see any 'Select All' option) and I got an internal server error:-
---------------------
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator at root@localhost to inform them of the time this error occurred, and the actions you performed just before this error.
More information about this error may be available in the server error log.
-------------------
I already added one complete ticklist by the same method and that worked, this one fails consistently, possibly because it's bigger, more than twice the number of entries.
