When enabling “Bulletins” the slug gets changed to match the “Bulletin Tab Title”.
It is, however, possible to then rename the slug as required…
This explains something that’s puzzled me for a few weeks… why @Phoole’s links have not been her usual show numbers…
Wow, thanks for the report and excellent debugging work @FidgetStudios!
The old form validation code is a bit hairy. It seems that the bulletin tab title field was copy-pasted from the slug-field and some of the related actions still point to the original. Luckily an easy fix, will be added to the next release
