Sorry about that and for being so late getting over here. I found that a number of forum settings were incorrectly pointing a test forum I had here. It appears that while I was working on that one at some point while logged in here SMF used one authentication session for both. Thus without me realizing it, SMF reset these forum settings to those of the other forum.
My work with the other forum setup was complete and those forums were no longer needed so around 1am I deleted the test forums and its database. Then, these forums couldn't find the images and CSS they were looking for. I was done for the night, so I didn't notice the effect over here. When I did see our forums awhile ago, I realized the settings were corrupt, so I ran a php tool created by the SMF team called appropriately enough, "repair settings." It would seem I'm not the only one this has ever happened to.
Anyway, sorry about the dumb issue.
