Hi Rebecca. It’s probably either a form validation problem (and maybe your theme doesn’t show the error messages) or something weird happening with something known as the “nonce.”
I can see you are running the BP Template Pack, which is good. Have you overridden any of the files provided with the BP Template Pack in your theme?
Thanks for the fast response!
By overriding, do you literally mean taking the “registration.php” info from the template pack and replacing the main themes “registration.php” ?? If so, I just tried to do that an it didn’t change anything (same thing with the activate.php file).
Unfortunately, I’m not sure what a “nonce” would be, sorry about my lack of skills!
Here is the next portion of this ordeal:
A random person was just able to sign up, but nobody else can still??
OMG I feel stupid, but i figured out the problem. My template doesn’t truly support buddypress, so I had to manually write in the information to tell users to only sign up with a username of all lowercase letters. It actually clicked when I thought about signing up at this site. oh my gosh!!
Okay, so I still have one more issue however. When I try to make a “group blog” page as an admin of a group, I get a fatal error message: “Fatal error: Call to undefined function wpmu_validate_blog_signup() in /home/undivide/public_html/gamercookie.com/wp-content/plugins/bp-groupblog/bp-groupblog.php on line 524”
I’m guessing you’re using WP single/standard, and not WPMU/WP Multisite. The BuddyPress Groupblog plugin was written for WPMU/WP Multisite. The function, wpmu_validate_blog_signup(), is a WPMU/WP Multisite only function, which is why you get the Fatal Error. Because of the nature of standard WP versus WPMU/WP Multisite, I don’t expect you’ll get the group blog functionality on a standard WP installation… not anytime soon at least.
I’m using WordPress 3.0 which I thought had MU integrated into the core.
It is true that WP and WPMU were merged in 3.0, but the MU, now called Multi-site, functionality has to be explicitly turned on. Since you don’t seem to have the wpmu_validate_blog_signup() function available to you (as revealed by the fatal error), I’m guessing you didn’t explicity turn on multi-site, or you didn’t do it properly. The WP developers added a few hoops to jump through to enable multi-site to discourage the casual user from borking their site. These hurtles will be removed in a future release, likely 3.1, when the developers have more time make it user-friendly for most users.
Thankyou for replying so quickly! So, you were right. I’m a wordpress noob.
Anyone who is having similar problems try this walk through to PROPERLY set up the MU feature: http://wpveda.com/wordpress-3-0-enable-wordpress-multisite-tutorial/
Otherwise everything is better now
