Hi Adam,
Thanks for your answer
I've done a local fresh install with the last version (5.0.5)
my environment is Debian Jessie and I choose to test install with database postgresql 9.4
All dependencies required during installation are installed
Right on directory are 755 (chmod)
<code>ls -la /var/www/html/
drwxr-xr-x 15 www-data www-data 4096 sept. 16 19:58 ilias
</code>
I join error log on txt files, recurrent error is : ERROR (unknown): MDB2 Error: unknown error
Hope that will help you to help me ;-)
