We'll be running some maintenance which includes turning off the setting of subscriber groups and trust level 3 groups for now, until the Discourse development team fixes a bug on their end.
We're also re-configuring the server to accept larger images, since we think the issue with image uploads has been a 2MB file size limit. We're going to set the limit higher and see if that solves everyone's upload problems.
Changing that value requires a server restart, so we may as well take advantage of the downtime and upgrade the forum software. A few bugfixes have been submitted over the last few days, and while I dont think any of them were ever bugs that were specifically mentioned on here, who knows.
I'll post back in here once everything is done.
