Post installation

If you go to http://www.thinkingpost.net you can see that drupal is showing the default page that you get whe you first install drupal. However, when you are logged in, the proper content shows up. I have everything set to that anonymous viewers can read the articles too. But to submit them you have to creat an account.

Why would it be doing this?

The Trackback module currently appends received trackbacks for a node to the node body using the trackback_nodeapi() function.

This approach has the following problems:

I have had to disable captcha module in the mean time to not block registering users and I can get rid of obvious bots on my own as they come in for the mean time. But for some reason, and I have GD2 installed, captcha module does not show the image to type the letters for authentication.

Why might it be doing this?

I have 4.6.4 and it happened in 4.6.3 too.

If there is anything else you need to know, please let me know so this can be resolved as soon as possible.

I keep getting those and I am wondering why. Seems like it is trying to insert stuff into the cache that is already there. I was wondering if there is anything I can do to avoid this.

All right, so I played with the access control (I think) so that people can't create usernames that have "admin" in them (deny %admin%). I thought it would only apply to new usernames. I guess I was wrong, and now I can't login because "The name admin has been denied access." What do I do now? :(

I'm a newbie. I wanna know how I can be kept updated with each module I added. Is there any way (RSS/Atom or e-mail) to get a message every time specific modules are updated?
