OK, this has been fixed and the site is running and the Admin is good
The problem was that somehow the upgrade was not successful, so XOOPS got stuck. You couldn't run the upgrade anymore, and the Admin was partially blank, incl. the Module section.
So what I did was to run the Update of the System directly from URL. I added to the URL: this code:
modules/system/admin.php?fct=modulesadmin&op=update&module=system
so it created this URL:
http://mysite.com/modules/system/admin.php?fct=modulesadmin&op=update&module=system
That allowed XOOPS to complete the update and now the Website is fine.
I hope, if somebody gets stuck after an upgrade, this might be helpful.
