vBA CMPS Question: 3.5.2 forum upgrade breaks my CMPS... advice please

[TheMusicMan]

I just upgraded one of my forums to vB3.5.2, and the forums work fine but now when I try to access the vBA CMPS Portal page I get the following error;

Fatal error: Call to undefined function: print_portal_output() in /*****/*****/public_html/playgroup/index.php on line 35

Can anyone advise what might be happening here please... it worked fine on vB3.5.1 but not vB3.5.2

Thanks.

PS: Line 35 is

 print_portal_output($home);
