I got much problem to install myxoopsforge download from http://dev.xoops.org/modules/xfmod/project/showfiles.php?group_id=1&release_id=22
I'm using XOOPS 2.0.6.

1. xf-mod configuration can not update email, cvs_url, cvs_script and tab_menu.
2. xf-mod group maintenance return error (about header.php member or object)
3. xf-mod news admin can not submit because thereis no groupid
4. many warning and error.

I try to download cvs version and got the same problem.
problem #1 resolve if I put manualy cvs_url, cvs_script, dl_url, and tab_table at table xoops_xf_config
I think there is missing line at modules/xfmod/sql/mysql.sql to insert that record int xoops_xf_config table.
problem #2 solve if i delete $_SERVER['PHP_SELF'] from ArtifactHtml.class at global definition line.
problem #3 resolve if i put $group_id = $_GET['$group_id'] ups forget which file. must searching first :)

The question is there is other script somewhere that i not found or what ? I see dev.xoops.org running with no problem.
