There are a number the explanations I have for you...
The forum maintenance mode was activated by me while I contacted my host provider to discuss security concerns with the php scripts of this forum. After addressing some of these, I reactivated the forum.
The "sorry folks" image was from May and that file should have been deleted, but I never got around to it. All of my "write" permissions were reset, and I have to manually reset them to delete or change any files. Fortunately I have figure this conundrum out, but that is why the sorry folks image was in place briefly...
The error messages from earlier this evening were caused by me upgrading the forum to the latest version of SMF. This is now complete...
Your avatar changed, like mine did, because I reinstituted an older version of the forum files/scripts I had saved from May 14, 2009 in place of the most recent ones due to concerns with the security of the php scripts.
There may or may not be another change to the forum in the coming days. Please bear with us on these changes...
