Fatal error: Call to undefined function: drupal_set_html_head() in c:\program files\apache group\apache\htdocs\modules\htmlarea.module on line 121

I'm trying to use the HTMLArea module on my intranet site. After I enabled the module, I receive the above error message whenever I click on Administer->Configuration. I'm also using the XTemplate theme.

Hiya guys.

This maybe a very stupid question, but, I've searched everywhere for a possible solution.

Sometimes when I log out or try to access the index.php page, the browser tries to download it as opposed to opening it. i.e. sometimes a dialog box appears saying "downloading file" and it downloads index.php, asks if I want to open/close or cancel. When I click on open it, it says it doesn't know what to do with the file.

Am using drupal 4.4.1
on an apache server.
don't have access to php.ini on my server and am not using htaccess

I cannot get avatars to display with 4.1, I'm using space from 1and1, and have clean urls enabled.

I've enabled avatars for posts and comments in my current theme, I've also changed the avatar rules to read 1000x1000 & 5000kb, I'm only trying to display a small gif.
I've tried jpg, gif and pngs. And after a picture is uploaded it does land in my avatars folder, but the site doesn't display it.

If I have a default avatar set, the site displays that fine. I also had the same version and setup installed on another host to test, and avatars worked fine there.

Don't know what is causing this. Basically, I'm using the book module to organize articles I've wrote. This is nice because it allows me to split long articles into multiple sections. I then use the cmx's article module to access the book pages.

When the Who's Online block says "36 guests online" does it mean, some 36 users accessed page within the last 5 or so minutes. Cause I see around 20-40 guests online 24 hours of the day. Are there any pointers on more information on how the block calculates the number of guest, if this topic was already discussed before? Any help appreciated. Thanks.

Vishal.

Is there a way to automatically turn off comments for older posts?
I could do this probably with a simple SQL statement, but it would be nice to have a automatic process which disables comments for old stuff.
