Installing Drupal

I installed Drupal and I get this error message when i visit my site
"* warning: include_once() [function.include-once]: Unable to access ./themes/engines/phptemplate/phptemplate.engine in /hosted/subs/ulmb.com/h/a/hasbeenhere/public_html/includes/theme.inc on line 78.
* warning: include_once(./themes/engines/phptemplate/phptemplate.engine) [function.include-once]: failed to open stream: Unknown error: 0 in /hosted/subs/ulmb.com/h/a/hasbeenhere/public_html/includes/theme.inc on line 78.

I tried installing those files but it "This file extension is not allowed"
What do I do?

I know :P I install alot of forum/cms
-FORUM-
PHPBB
SMF
MYBB
YABB
PUNBB
IPB 1.3
Burning Board

-CMS-
PHP Nuke
Post Nuke
Drupal
Wordpress
b2evolution
nuke-evolution

Everything has error None of them working fine. due to file extension that are not allowed. and php send mail function also sql

I think this new PHP version 5 and SQL 5 are not stable as PHp4 and Sql v4...

I have allowed .engine files for drupal.

If you have specific errors with the other scripts please let me know.

I got the phptemplate.engine installed but now it comes up with this error
"Fatal error: Call to undefined function filter_xss_admin() in /hosted/subs/ulmb.com/h/a/hasbeenhere/public_html/themes/engines/phptemplate/phptemplate.engine on line 143"
Do I have to edit something in the phptemplate.engine file?

According to www.php.net there is no such function filter_xss_admin

I can assume that this is some function that only exists in drupal.
You need to contact drupal support.

I am also trying to install drupal, i got past most of the problems, but the newest problem that arose was that i couldnt upload .module files. This leaves me with a

Fatal error: Unknown function: node_get_types() in /hosted/subs/ulmb.com/l/o/lomarb/public_html/community/includes/theme.inc on line 248

which the drupal website says is placed into the node.module file.
I was wondering if it were possible to allow .module files.

Thanks.
