If you want to report a #
Hubzilla bug, and you don't have a Framagit account, you're currently completely out of luck.
Framagit has closed registrations until further notice to combat a flood of spam.
And the @
Hubzilla Support Forum is out cold. Zotadel, the hub that it's running on, has been offline for two days already, it doesn't have a clone, and nobody knows how to get into contact with the admin who seems to be AWOL.
The latter alone should teach you to have at least one clone of your channels if you seriously want to stick with Hubzilla. This goes even more for forums which should also reveal where their clones are.
