Im running vb4 gold pl1 and vbseo 3.5 rc1 and when i enable the JS compression and run the js compression tool i get errors where the site is just a white page with a few links on it, and i get this message which is strange as ive run the compressor (several times) :-
Please run the Compress JS function of vB4: SuperCharged in your Admin CP.
Your forum is currently running without optimised Javascript as a fallback.
As soon as i set the Enable JS Optimiser to no the site returns to normal.. its running ok with the css optimiser though..
Good hack though, noticed an improvement straight away..
