Sorry for the late reply. Had to take a break from the site as other things came up.
I have some good news. The ext for testing called 'boardrules' shows up. However I can't seem to get any other ext's to show up. One I really wanted to use was phpbb gallery. I put the main folder for it into a folder called 'subblue' since it is the creators nickname for it. It just wont show up. I tried moving the directory around, etc, and nothing. Shall I put in those files you mentioned above? Please let me know what you want me to do. I will gladly give you admin rights or whatever you need to help me figure this out. Thanks a ton.
Update: I went ahead and put that file in the root of my phpbb install. Hope this helps.
Also here is the MOD https://www.phpbb.com/customise/db/mod/phpbb_gallery/
Forgot to mention this. sorry
