I had installed XOOPS 2.0.10 and now i'm having a problem that i would like to describe detailed: (for those impatients the error is at 9th item below)

* Apache 2.0.54 (with libphp4.so)
* PHP 4.3.9 (with mysql.so)
* MySQL 3.23.58

In php.ini allow_url_fopen is "On". XOOPS was untared in the document root, after this i chowned files to my apache user recursively (for testing purposes) and chmoded to 755 the following files/directories:

cache/
templates_c/
uploads/
mainfile.php

1) I begin in installation screen (here http://localhost/);
2) selected "English", and next;
3) Reviewed instructions, next;
4) All write test to above files/directories has passed, next.
5) Entered the following values into "General Configuration", and next.

Database Username: xoops
Database Password: password
Database Name: xoops
Table Prefix: xoops
Use persistent connection? No
XOOPS Physical Path: /var/www/html
