Photoblog lite is not working

[Goodman_2020]

I installed photo blog lite on my forum. Installaion 100% ok, everything is at his place........but (like always, because whatever i install it seems to never work for me grrrrr) no changes. I set the photoblog mod on "on"... nothing appears on my forums. I set the persmissions for users too, create a test category etc... nothing to do, nothing appears, not even a little menu....

I use 3.6.5 version of vbulletin

I think the problem can come from a field where i don't know what to put: "photoblog link"... it can be the only reason why it's not working, if no, i don't understand.

Then what adresse should i put here, i didn't understand.
I don't have a website, it's just a forum, so the adress of thewebsite is also the adress of the forum, and is build liek that : http://blablabla.com/index.php or http://blablabla.com/

anyone can help me? thx
