Strange 500 error, disappears when in debug mode

[VMT]

Hi all,

I'm using 1.7.4.4 and I just attempted to go into my admin back page. I can successfully login and load the dashboard, but the moment I attempt anything further like products, shop parameters, advanced parameters or modules etc. etc. I get a 500 error (in Chrome at least, firefox just gives a blank page).

After some googling of how to enable debug mode via ftp as I could not access the advanced parameters area, strangely the admin back pages work. All of them work in debug mode without 500 error. However the moment I disable debug mode, all the issues return.  Frustrating as I don't know what the 500 error is to fix further if debug mode won't show a failure.

I've attempted this with Firefox & Chrome, and different computers too, to double check it wasnt something on my end.

Any assistance on how I should fix this or what next debug steps to take?

How do I correct the access denied error?
