Using Hyperion on J1.5 has worked fine with both RokContentRotator and RokIntroScroller for a year.
This weekend I moved the website from one hosting account to another (but with the same company, GoDaddy).
I restored a back-up of the MySql and uploaded the Template.css, demo.css, and images file from the original website onto the new one.
Everything looks great EXCEPT that RokContentRotator and RokIntroScroller do not work. At All. I have tried everything under the sun. Installing, un-installing, restoring from old site, using clean installs from new site... nothing is working.
Don't use the previewdns. I have found many problem with other members using this previewdns. You can set up your site temporary in subdomain like
www.yoursite.com/temp/
instead of using previewdns.
