Suspect the error message is related to the capacity of the comment
fields. If you write too much it overloads the database and
chucks a spaz, hence it is working for some and not others.
Try filling it in without commenting and see if that works for
you...
Exactly right - and my fault. I'm working on a fix now, which
should be sorted in the next hour or so.
My bad - no fault of the club.
