Nevermind, i found the piece of code that was going wrong....

Line 449 of header_php.php

PHP Code:
if (PL_SHOW_MODEL == 'true') 
needed to be changed to:

PHP Code:
if (PL_SHOW_PRODUCTS_ID == 'true') 
Only thing is - there is no switch made for the front end to turn this on and off...might have a look at that in the future and send it to you for a future update...

Cheers!
