[SOLVED]PHP Warnings during ISPCP Operation

[Martini]

Hello everyone!

I have a strange problem with my ISPCP Installation.
I use ISPCP Omega with CentOS 5.5 on an i386 arch.
The install of the ISPCP and the base system itself went pretty smoothly without any errors, but things are getting out of control during day-to-day usage of the system. Each time I log into ISPCP I keep getting PHP Warning Messages - regardless of which part of the panel I'm in (e.g. the WebFTP module). I've already tried to silence these warns by altering the value of error_reporting parameter in /etc/php.ini, but it's all for nothing.
I've attached 2 screenshots to this post showing different examples of the above mentioned warning messages - hope this gives you a clue on what exactly is wrong in my setup.
Any help would be much appreciated, thanks in advance,
Martini
