Installing Drupal

I have installed and reinstalled themes, but they only work on the themes page itself. The theme doesn't carry over to the home page or elsewhere on the site; only were themes are administered. Thanks for any suggestions.

I am getting this error
Fatal error: Call to undefined function: mysql_connect() in /var/www/drupal.4.5/includes/database.mysql.inc on line 31

Please help me to solve it.I have followed the installation instruction and I am successfull in installing in one system.But for the other system I am getting the above error

I'm trying to install drupal, but I seemed to have run into a problem when I go to my site.

Warning: main(includes/bootstrap.inc): failed to open stream: No such file or directory in /home/torranc/public_html/mysite/index.php on line 12

Warning: main(): Failed opening 'includes/bootstrap.inc' for inclusion (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/torranc/public_html/mysite/index.php on line 12

Sorry for my English. I've been triying to install Drupal 4.4.2 on a free host server www.freelinuxhost.com . At the begining I got the error 500 internal server error so i change my htacces for htaccess_inactive but now the problem is that when i try to load my web site only a white screen is showed www.anxo.thefreebizhost.com

Thanks for your support.

I was running CVS version from late august and I figured some files were updated since then so I did the upgrade but had a tough time. I just started fresh with 4.5 since I didnt have much content yet.

Now that I am setup again, I cannot seem to access the admin areas 'content' section without getting the authorization alert.

Another oddity is the 'Input Format' area of form to post content appears before and after the body textarea, no matter which theme.

I've just installed the banner.module and it seams to work OK, but I was doing some testing on a develpment site before I moved it to the live site and I'm having problems with displaying multiple banners on one page.

One banner works OK, I've put in into a block unsing the code
return banner_display(0);
with the block set a php.
