My custom header image code will be inactive for a bit while I update it to match a theme update. Which may be a day or two as I'm going into "entertain some guests" mode right now.
In case any of you cared :-)
[Update 10:30 PM] Apparently the old theme Category code is broken with the new WP update as well. Apologies if you see weird error codes hanging around for a bit.
[Update 11 PM] Basic errors fixed. Onwards to the headers.
[Update 11:15 PM] Fixed. Please let me know if you experience any glitches.
