[Typo3] $conf Array in Plug-ins is almost empty

[Sauerborn, Timm]

Hi List,

I've noticed a strange behaviour in my front-end-plugins. Unfortunately no
Plug-in does work anymore because the only value which is commited as
$conf-Array to the main-Function of any plug-in is: userFunc. Anyone has an
idea, how to resolve this issue?

I already searched over and over, but the only posts I have found about that
are unanswered so far...

I'm using TYPO3 3.7.0 on an Apache-WebServer (Windows) and mySQL 4.0

Thank you in advance, Timm
