It’s been a while since I logged on as site admin to my other site Wiivil Computer Help. I tried all the passwords I can possibly think of and none was correct. Being security conscious I have different passwords for the many credentials. But that is hard to manage as I have to remember all the passwords without writing them down somewhere. Now, I am locked out of my Network help site. Luckily this is a common occurrence and there are solutions available. Simply doing a search on the internet reveals many solutions.
Well the fix that I use requires access to the MySql database for phpnuke. PhpMyadmin is suggested as the means to access the database.  Since I use Navicat for all my MySQL databases backup I decided to use that. It does the job just as well as PhpMyadmin, I have both installed on my server.
Here is the instruction to change it the admin password.
Using Navicat go to the nuke_authors table and make your pass dc647eb65e6711e155375218212b3964 that will make it Password, then just login and change it.
