The 15.0.3 to 15.1 migration went great until we started to look at communities.
In Mozilla the pages all look as designed. We viewed with IE picasso effect.
I have examined this highly customized site with Mozilla Fire bug and the http://jigsaw.w3.org/css-validator/ .
After fixing tons of CSS errors that had accumulated over the years the communities problems still remain Picasso effect in iE.
VS 2005 adds carriage returns to CFM pages.
Basically a few CFM pages were corrupted by the vs2005 editor.
The additional table break is still an issue on the eCommunities site but the header is now fixed.
