Well seeing that the phpbb3 solution is not found, I moved to Phoenix because Icy seemed better and I just installed, and I get just after installation of the form:
Could not get theme data for themes_id 
Line : 1045
File : functions.php
What could be?
Template (s) usuada (s): The default
MODs installed: None
Icy Version of Phoenix: Phoenix Icy 184.108.40.206 RC 3
Patches Installed: None
Server: Payment 1and1
If an updated version from another Icy Phoenix: No.
If an updated version from another XS: No.
If an updated version from another phpBB: No.
