Something’s screwed up with the new blogads code. I’ll have it fixed tomorrow at noon. Sorry for any inconvenience.
Update 1: apparently blogads is sending a preformatted style with the ad that creates an extra < li > or < ul > which I can’t overwrite… email has been sent to blogads. Will be fixed asap!
Update 2: okay, after a few hours of messing with the code, at least the ad is now customized. I still have the list item and can’t overwrite it yet. Waiting for feedback from blogads to set it straight.
