Re: Help On Adaptation
-----------------------------------
Let me explain some things :
First of all this forum is originaly created on phpBB 2.x.x and modded with Category Hierarchy. This last changed a lot of things in the forums that's why, before upgrading to IP, I put my forum on phpBB 2.x.x WITHOUT CH ( category hierarchy ).  As you said, every forums have a cat_id = 0 but nevermind because in the categories' table I changed the value to 0 too then in phpBB 2.x.x I got every forums in the same root BUT it was displayed. 

Here you will find a screen of my forum under phpBB ( simply ) :
The Index : http://d4.e-loader.net/roWKgBOHea.png
ADM Pannel : http://d7.e-loader.net/AzStm84aZF.png
( be careful there's many sub-forums so it make very long screenshots because, as I said, every sub-forums are now on the same root ).

[...]

I just thought about something ... You talk about def_tree.php and I just opened it : it's very similar of the conception of full_tree.php ( in the cache ). Then I tried to replace def_tree.php with full_tree.php but it did nothing. I think the solution is close of something else but I don't know where =(
Then I put my files here :
/common.php = http://d5.e-loader.net/i8LN3vDRlI.txt
/includes/def_auth.php = http://d12.e-loader.net/Ip1AzGihse.txt
/includes/def_tree.php = http://d12.e-loader.net/kc4kcd6b32.txt
/cache/full_tree.php = http://d13.e-loader.net/CTKlB8umJb.txt

I hope that will help you ( to help me >.<' ).
Thanks for your help and your patience =/

EDIT : My version of IP is this one : http://code.assembla.com/icy_phoenix/subversion/nodes/ip/trunk
=> Isn't it possible to create manually every sub-forums and to change every id for make it ok ? =/
