Hello. Yes. I noticed that as well … at some point this happened and I don’t recall doing anything that could have caused that. I’m not too good at debugging these wordpress sites, any idea where I can turn to figure this out? Any articles I could read would be helpful … I literally have no idea what to look for.

I see it’s having trouble with some lists I have in these popup modals (it’s a plugin) … but when I examine the code in those lists, it all appears to be right. Dreamweaver is good about getting your attention with different colors and such when there is a an html or css syntax error, and I don’t see anything like that in the code I’ve pasted in.

A lot of the validations errors appear to have to do with the slider which is built in to the theme. I don’t even know what to do about all of that. Aren’t hacks the norm in extreme CSS endeavors like that?

Hmmm … most of the validation errors have been cleared up and it still doesn’t display correctly … this is a weird one …

Issue resolved. There was an extra quote in a css rule
