Since the MODIFICATIONS don't work on custom themes, I've taken upon myself the task of manually adding them to our new themes!
I ended up clearing all the modifications and well, the 4M itself and boiling it down to the basic php coding of the latest version, but...
doing so caused the 4M to crash hard 4 times, which took me hours to reinstall everything and purge the mashed coding...
Sucess was just around the bend: I have gotten the gallery to work! (the button needs relocating) aaaaaaaand I've also gotten two other MODIFICATIONS to work!
38 MODIFICATIONS to go on the 4M Theme and I'll have to do it all over again for the other themes.
