I'm in a big puddle and would appreciate your support.
I installed your plugin last year (v 2.3.3) and really liked it. We haven't upgraded since and really need the categories view. I tried upgrading directly and manually to 3.0 and the website homepage went blank and replacing the lib dir gave some rewrite.php error.
Please advise on the best way to upgrade your plugin without losing my categories and content.
With much gratitude ... an accidental techie
