Can't get wp-signup.php to work for a new user to register a new blog

I apologize if this has been answered but I have searched and I cannot locate an answer to my problem.

I have Multisite set up on my site and have about 13 users and 14 blogs currently going. At present I have manually entered each new site when they have registered. I would love for new users to be able to register their own blogs when they come to my site. I am trying very hard to get the wp.signup.php to work but so far I am getting errors.

I have tried a method where you modify the htaccess file and copy the wp-signup to the theme and that is not working and I have also tried just doing fetblogger.com/wp-signup.php and it just gives me a Warning and a Fatal Error.

I wasn’t sure if I could post the errors here or not, so I didnt. I’m pretty positive I could recreate them if needed hahaha ??

Is there someone who could just walk me through setting up my network to have users register their own blogs?

btw yes, I do have the Network settings set to allow both Users and Site registration.

Thank you in advance for your help on this. As a warning I’m not very good with all this code but I am quickly learning.
