If you looked at this site between Saturday evening 2/10 and just now using IE, it looked like everything had gone to hell in a handbasket. Which it had. No problems in Firefox, though.
This is the one case I know of where Firefox didn’t hold the coder (me) to HTML standards. Usually IE is the one that will let you slide with stupid stuff such as not closing your table cell tags.
Saturday night I was mucking around with my Textpattern pages and forms in order to make excerpts of photo galleries appear on the front page. That would not be a big deal except I have three different methods (one personally deprecated) of posting photos. Exceptions to exceptions to exceptions.
Apparently, I (or Textpattern, not pointing any fingers here, Texpattern) introduced a space in comment code. What should have been
--> instead were
<! -- and
-- >. That just gave IE fits, but Firefox let it skate.
