Not sure what exactly you are referring to:
PHOTO UPLOAD TO THE JOIN NOW SCREEN - So many mods and alterations it is tough to keep up with them all.

A mod, or some kind of block addition or other. If you replaced or edited any other files just replace the ones you edited/replaced/or modded with the original.

If you replaced only :
inc/classes/BxDolProfilesController.php replacing with original should fix it, unless you possibly modded another file or another file you did mod is relying on see more this or another file to make it work.

unexpected T_VARIABLE, expecting ';'
line 24 is just a blank line. The line right before it 23 is:
$this -> oPF = new BxDolProfileFields(100);

Make sure this line has the ;

If you are copying and pasting make sure you didn't miss any code.

Otherwise are there any other pages you edited.
