Hi!
I upgraded a couple of days ago to nbill 2.3 from 2.0. I used the patch provided, since I had locally modified some custom files.
The upgrade requested also the database to be upgraded. No error message was shown up and at first all seemed ok.
However when I try editing and saving changes on anything e.g. a contact, a product, an invoice etc i get
The server encountered an internal error or misconfiguration and was unable to complete your request.
In server logs for example when changing a product
[Tue Jan 03 16:11:59 2012] [warn] [client 62.169.208.167] (104)Connection reset by peer: mod_fcgid: error reading data from FastCGI server, referer: http://www.weballdesign.gr/administrator/index.php?option=com_nbill&action=products&task=edit&cid=25

Same thing from frontend when trying to change user details
When I used one of my forms to create a new order, it proceeded succesfully creating a pending order, however when I tried to enable the order I got same message
In joomla everything seems to work ok, editing, installing etc
I am using debian squeeze with php 5.3 and joomla 1.5.23. with mod_fcgid and suhosin
I downloaded the patches you have in known issues but nothing changed
Please help me figure out what might be the cause..
