This is also still happenning to me. I just upgraded from XOOPS 2.2.2 to 2.2.3a final. I am geting the following error messages:

Warning [PHP]: Invalid argument supplied for foreach() in file L:\WebSite\.....\modules\xcgal\ecard.php line 89
Notice [PHP]: Undefined variable: xoopsConfig in file L:\WebSite\......\modules\xcgal\language\english\modinfo.php line 97.

I have uninstalled and reinstalled scgallery. I even downloaded a fresh copy of the module.
