Today I succesfully updated (I think:) first from XOOPS version 2.06 to 2.07 and then to 2.092. Everything seems to work just fine (exept the forum module, but that is an whole different issue), but when I go to the "Module Administration" section, I get the following messege:

Module File for class Not Found!Module File for Not Found!Module File for Not Found!Module File for Not Found!Module File for Not Found!Module File for Not Found! Module File for include Not Found!Module File for Not Found! (and again and again....)

Also, a lot of empty modules are listed at the bottom. What can I do?

check the file structure. You seem to have quite a number of subdirectories to the xoops-root/modules that are not modules.

Whether they are core files unzipped to the /modules instead of the root or whether it is a module that is unzipped to /modules instead of /modules/[modulename] I cannot tell from the error messages.

tnx. mithrandir! That tackled the problem.

While uploading I made a rookie mistake, to shamefull to mention here
