I had subscribed to a category on my Nabble forum, and went to unsubscribe under the options menu and I got the "Error 500" message. There is a huge error script that I can email if you need to look at it. Any ideas?
Check to see if the unsubscribe action has worked (The menu will say OPTIONS > SUBSCRIBE VIA EMAIL).
If the option still indicates you are subscribed, try again. Often errors will clear themselves.
If you get the error again, post the entire error message here so one of the Nabble team can get to the bottom of the problem.
Volunteer Helper - but recommending that users move off the platform!
