I have the same problem. I thought it was somewhere in my settings that caused it to not display in IE 7/8. However, when I went to the example site that was listed on the main page of the Plugin, it also does not work in IE 7/8.
Please let us know if we can get this to work in IE. Thanks!
Nevermind, I found out the problem!
cats=”Album1_10 % Album2_10 % Album3_10″
must be
cats=”Album1_10%Album2_10%Album3_10″
I can’t have a space between the % symbols!
