Vbulletin 3.5.4 and cpg1.4: bridge not working

[Arnaud]

Coppermine install: http://campaigns-france.org/gallery/
Forum install: http://campaigns-france.org/forum/
Coppermine version: cpg1.4.4
Forum version: vbulletin 3.5.4
Test user account: test/test123

BridgeManager settings:
Forum URL:  http://campaigns-france.org/forum/
Relative path to your BBS's config file:  ../forum/
Use post-based groups?:  0 

I set up CPG alone and it worked fine, I uploaded one jpg for testing purpose.
I bridged CPG to my vbulletin. No error messages.

I used same login/pwd/email in CPG as in vbulletin. Cookies names are differents

When I return to my CPG page, I can't login (the redirect url is working but that's all) as member in CPG, as admin in CPG...login in vbulletin is working fine.
I do not understand what I have done wrong 

thanks for your help

Cookie path must be set to '/' by your forum.

In CPG config, the cookie path is set to "/"

You need to set your cookie path to '/' in your forum, not Coppermine.

Great! It works!

Thank you
