404 Not Found

Nope that didn't work either.

I even unpublished the plugin and still didn't work.
I cleaned the cache and still nothing.

I have another site that it works fine. I've looked
at both sites configuration and both are exactly the same.

Strange

Don't know what is wrong, but submit goes to this url:

Unpublish non-core plugins 1 by 1 within CB > Plugin Management to see if it's a CB plugin causing problems. Typically though you should see an actual error. In your case it seams to be trying to send you to a page that does not exist. What is the URL in your browser when you see that error (you can remove domain)?

Have tested your registration in Chrome. I was able to register perfectly fine. You should see a "testreg" user within CB > User Management. Are you able to confirm this issue or are you just basing the issue of reports from users?

Check your Antispam settings

As I continue to look into this in a prior message I was told that the url was pointing to iaabo27.org/www.fbi.org.

So I am using AdminExile. I had the url pointing to the fbi for anyone trying to log into the admin account.
So I unpublished it and then cleared the cache. I then uninstalled the program and Unfortunately when I tried signing up again it still points
to the fbi.org site.

Now there are people who are still able to sign up and some not being able to sign up.

this is very strange. Is there a code for the submit button that probably pointing to the
fbi.org site?

thank you for your help
