Ok.. I finally figured out the problem when your registered users get that error that says the user is not found in the database. This is a very easy FIX. But before doing anything, back up your database!! I warned u.. Don't complain if u loose ur site..
Ok, moving right along..
Make sure you have uploaded all of the correct files and you have PHP Nuke 6.5--duh..
Now download nukesql.php from NUKECOPS, http://www.nukecops.com, Upload it to your site and visit www.yoursite.com/YourNukeDirectory/nukesql.php
Click fresh Install, DO NOT REPLACE YOUR Tables!!!
Make sure you have the same MYSQL database info in your config.php when you had the user error. Now go to your site and adjust your blocks. Some of your blocks will be shifted around, but they will not be deleted.
Your DONE.
To Test it, register for an account...
I Certainly Hope this helps a a lot of people who have this error.
Thanks.. And Good Luck
