The Dark theme was causing the forum update to crash and the server as well, so it had to be removed ad re-added. Not sure if this means you will need to reset it as your default theme in the preferences area.
Bright light, bright light! 
Dear Gizmo,
I re-added it, but you may have to re-select it in preferences now.
Cheers,
Jim
Thanks but I am not responsible for Stripe and his brothers.

Hmmm… Preferences? Where might they be?

In a locked cabinet.
under the stairs.
