I was having problems in 2.3.x with a few modules (news, iStats, eXtgallery) in the admin menu with XoopsInfo installed and ThAdmin in operation (disabling ThAdmin, but left installed worked fine). After searching I found several postings related to the same problem (here, here, and here) in XOOPS 2.0.x and 2.3.x with similar symptoms.

The error I got when visiting any of the affected modules was
So, I fixed it with this hack. In the xoopsinfo/include/functions.php file, enclose/wrap the function adminmenu declare like this:
This prevents the function from being declared here in XOOPSinfo when other modules are in operation. Hey, it works, and hopefully it will get fixed. Not sure if it's a problem with ThAdmin, but I expect more likely something in XOOPSinfo.

All modules should prefix their functions that's why.
Guess the problem is in both modules.

Absolutely, agree on the function nomenclature. However, it's also interesting that the problem only exists when ThAdmin is installed (or XOOPSInfo). It works fine with just one or the other is installed, but not when both are. Anyhoos, FWIW....

Marco has developed a "Quality Checklist" for module developers. If it's not already there, it should be probably added.

Hi,

Will be fixed in eXtGallery 1.0.5

Yours
