I'm currently in the process of updating and verifying forum security.
[EDIT] Victory is mine. While I still recommend backing up longer posts prior to submitting, I am no longer messing with stuff for now. Issue resolved until the upgrade.
What it means to you as the end-user is that you may experience being unexpectedly logged out when I change certain settings, so backing up long posts/replies before hitting "submit" is recommended at least for a few hours from now. Warning! Technical drivel below!
Currently, the entire forum should run on https (Secure hypertext transfer protocol) The security warning you may or may not get in your browser applies to mixed content images. I run the image proxy included with the software, but it does not seem to fix said warnings. Maybe it's just because I'm still within my old session.
Also, fixed the avatar path, enabling forum members to choose the avs from gallery. We can add/modify/download some generic nonsense if wanted and/or needed, but we'll take that discussion in tech-geek places.
I shall not use too many more calories on figuring out exactly where the current mixed content warning originates from as version 2.1 is just around the corner, and with it a force-SSL-across-the-board feature, which... Just better. If THAT still results in a warning, then back into the code I delve.
The upgrade will be performed once 2.1 is released. It's in RC2 now, so should not be too long. Expect the forum to be in maintenance mode for a time when that happens. I shall notify you closer to that date.
