It's the parse error. The reason why you dont see this module in the list you wrote is because this error halts the reading of this module and everything after.
Check your imenu module. Open the file xoops_version.php and check line 1.
I see Burning covered this issue in the comments for this module version 2.03.
This commentsCheck to see if line 1 is like this.:
['name'] = _IM_IMENU_NAME;
if so, change to something like this
$modversion['name'] = _IM_IMENU_NAME;
Programming is like sex:
One mistake and you have to support it for the rest of your life.
