Post installation

I had previously installed the e-commerce module, and it was working well, but in trying to resolve a problem with Wishlist, I disenabled the e-commerce module (as it was the last thing I installed before the problem)

When I re-enabled it, I now have 2 Address Book tabs in the User Profile.

When I go through the "checkout process", after entering the address, I get a civicrm error

I can upload .mov files using Acidfree 4.7.0 (09/09/2006, the latest version) and display them with no problems.

I just tried to upload a .wmv file, however, and got this error when I try to view the video:

warning: getimagesize() [function.getimagesize]: Read error! in [....mysite...]\includes\image.inc on line 89.

There is no window for the video to play in. In Firefox I can hear the sound and use the controls, but in IE not even the control box shows.

I want to build a website with a few categories of users :
- 1st category : artists which will display there work
- 2nd category : anonymous, or resistered users. These users will be able to tell what they think about the work of the users of first category
- 3rd category : some website administrator which will be able to do anything they want

I don't know of to define this category of users and how to assign users to one category.

I also want to make users of 1st category pay a fee for the usage of the website. How to do it (a module, ...) ?

I have version 4.7.0 (31/08/2006) of the taxonomy access module running on Drupal 4.7.3. Under "administer->access control->category permissions" I edit the permissions for a custom role and under "uncategorized nodes" I disallow any access (no view, update, or delete.)

Under "administer->access control->permissions" I ensure that the custom role doesn't have any inconsistent permissions, but there isn't anything specifically listed there for uncategorized content.

OK, this is a raw noob question, I know, but: I created a container, and in that container a forum, and in that forum a post, and in that post a comment. All show up fine when I'm logged in as admin, but when I visit as an anonymous user, or even as an authenticated user, I can click the forum link in the menu but I get a "No forums defined" message on the forum page. Where is the switch I have to flip, please?

It's been a few days the following error has been showing up in my log:

Cannot modify header information - headers already sent by (output started at /home/cultu3/public_html/news/includes/bootstrap.inc:545) in /home/cultu3/public_html/news/includes/common.inc on line 139.

the error is showing on random pages and not every time they are accessed. I wasn't able to replicate the error to caputre the HTTP headers, but the errors are still showing up.
