Registration has been disabled

Hello,
Can someone help me out with my site settings; I have been trying to setup the privacy option for multisites and when I try to add sites even though I set some rules for my levels using my membership plugin which enable paid users create more than 1 blog, all adding of new blogs keep redirecting to a page that shows
"Registration has been disabled."

I set the option to "Allow all visitors to all sites" but I still can't add new blogs.

I DID NOT DISABLE ALLOW NEW BLOGS.

Please help.

If possible, help me with a prototype of how the settings should be to allow certain pro members create more than one blogs.

Thanks,
Bro Louis
