*SOLVED* CentOS: lots of blank pages when submitting data

[_lunix_]

Hi,
When I submit data i get a blank page. When I click the browser back button the data was submitted properly.
This hapens as admin when creating a new reseller, as a reseller when creating/editing plans etc.
There is very little in the logs to show what is going wrong other than:

Code:

[root@nissan ispcp]# tail -f /var/log/httpd/error_log
[Sun Aug 10 17:03:16 2008] [notice] Apache/2.2.3 (CentOS) configured -- resuming normal operations

[Sun Aug 10 18:05:07 2008] [notice] child pid 11676 exit signal Segmentation fault (11)

Each line is when I submit a page. I have turned display_errors on in the php.ini and still blank page.

I have a real server with CentOS 5.2 x86 with all updates.
This was a fresh install today of the OS and ispcp-omega-1.0.0-rc6.

TIA
Mick
