BlankScreen - Login -

Dear,
to my System: check to options??.
I have 3 Problems with the use of my integration from the Bridge-Module in Joomala.
1) Blank Screen: it doesn´t matter is the index file pached or not. I turned the compression (gzip) off in both (SMF and Joomla)
Debug both patches "done":

TYPE: form action TYPE: href
2) ZoomGallery wont work (get an error):
when the 1st patch is done it isn´t posible to use the ZoomGallery.
- I un-patched the 1stpatch and the gallery is working.
Maybe can you intrped the error what comes, it is:
Fatal error: session_start() [<a href='function.session-start'>function.session-start</a>]: Failed to initialize storage module: user (path: /var/lib/php) in /srv/haus/vhhaus/components/com_zoom/zoom.php on line 65
3) Yesterday I tried the LogIn with the standart JoomlaLogIn and I dind´t get the usermenu. I think thats only a smal problem - didn´t it?

Hopefully you can understand what I meen. I am sorry for this maybe st$p$d questions, but Iam only a simple user and beginner. Anyway - Thank you for supporting me.
