I'm not the only one with this problem.
After instaling (Cpanel X - linux Apache- php myadmin) I found this message (after deleting htacces):
"Warning: include_once(config/main.inc.php) [function.include-once]: failed to open stream: No such file or directory in /home/original/public_html/extromail/program/include/main.inc on line 43

Anyone could help ??
I've tried for 2 nights.

Either you forgot to rename your config files from main.inc.php.dist to main.inc.php (etc.) or your PHP
has turned safe_mode on and restricts the directories from which files may be included.

If the latter is the case, then check out the php.ini setting "safe_mode_include_dir".

Thank you very much!
I will verify this night.
A forum will be allways a forum.
