Hi,
some additional informations.
Minitek Slider Pro works fine. You can see this on the site in the middle.
I have the Minitel Wall Pro-module deactivated, because the complete site doesn't run if it is active. After activating the module, the site crashed. If you analyze, please activate the module with your Super-User-Admin Credentials.
After analyzing, and if you didn't find the error, please deactivate the module, so that the site runs.
Kind regards from Jürgen
