I installed your program nukeseo on to my PHPNUKE7.5 files and the admin.php no longer works.
After you login it goes right to the index.php page?
This happened after i installed it and need to fix it so my admin functions work!

Please help.

Check the installation instructions (readme). It should mention that you need the latest patch version from http://nukefixes. You're missing a DEFINE statement in the admin.php, and probably the modules.php file, too. The patch will include that. There is another post here that details how to fix without the patch, but I highly recommend keeping PHP-Nuke current with patches.
