PHP User Warning: tempnam() [function.tempnam]: open_basedir restriction in effect. File() is not within the allowed path(s): (/home/user:/usr/lib/php:/usr/php4/lib/php:/usr/local/lib/php:/usr/local/php4/lib/php:/tmp) in ..../includes/class_dm_userpic.php on line 204

PHP User Warning: fopen() [function.fopen]: Filename cannot be empty in ..../includes/class_image.php on line 333

do you have any idea how to solve it ?

It is not vBSSO issue. You just have to configure vBulleitn. To resolve it set
Admin CP -> vBulletin Options -> Server Settings and Optimization Options -> Safe Mode Upload Enabled -> Yes
Then go to Admin CP -> vBulletin Options -> Server Settings and Optimization Options -> Safe Mode Temporary Directory and set the right path to your tmp folder (ask your hosting administrators if you don't know)

http://domain.com/forum//vbsso/vbsso.php?a=act&do=logout&d=http%3A%2F%2Fdomain.com%2F&lid=54129ccf8aae47.84842196

Go to Admin CP -> vBulletin Options -> Site Name / URL / Contact Details, find `Forum URL` and remove `/` at the end of the URL

Thank you.

Yes. You can do this by adding mod_rewrite rules to .htaccess file.
