[r3r3]

Well second problem this morning,

I run te RC6 on debien etch on a virtual server
Linux analog-data.ch 2.6.18-6-xen-vserver-amd64 #1 SMP Fri Oct 10 07:37:54 UTC 2008 x86_64


Yesterday all was working fine, but late in the evening i started getting a 500 error on the main domain, it run a joomla website, when i remove the .htaccess everything is fine, with with this standard joomla .htaccess, i get the error 500 :/

All i changed yesterday was the phpinfo in the php.ini

I really don't understand, anyone have a clue?
