As many of you have probably noticed, there have been some changes to the forums. Do to server changes, I had to update and re-install the forums. Nothing ever goes smoothly, as I had to make several changes due to the fact that some of the mods and the old themes are no longer compatible with the updated forums. The classic and dark themes were completely broken, and I tried and tried to get them working, with no success.
After much re-configuring and re-installing over again, I finally decided to revert the forums back to the pre-updated version.
This fixed the classic and dark themes! 
During this process, I moved all members to the newer Default theme, as it was unaffected by the changes. So if you were using the classic or dark theme, feel free to switch back. You can choose which theme you want to use by either going to the Home page and and using the Theme Changer (at the top of the left column), or go to your profile and change the theme by clicking on "Look and Layout" under the "Modify Profile" heading.
One change that remains is that there is no longer an actual front page. I kept getting errors. So now, the home page shows all the boards of the forum, as well as the Theme Changer, Links, and Recent Posts on the left column. When you click on the Forum tab at the top menu, or simply go to one of the boards, the left column will disappear. Everything else should be working the way it always has. If you notice anything that isn't working correctly, please let me know.
