Post installation

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.

Duplicate entry 'http://www.mysite.com/subfolder/index.html' for key 1 query: INSERT INTO cache

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?

I can't find any help documents online,

I haven't had this error before but when i browse to the "request new password" page I get the Access Denied 403 page - when I'm logged out and am a "anonymous user".

Any ideas?

Thanks in advance

Swtich to a new them on our Nintendo Revolution site and now the refferes are not working.

Any idea how to turn them back on?
