I have a WP site that uses gravity forms and the user registration add on using the email address as the username. Once I added the multisite, the site kept returning validation errors ie no capitals, email already exists etc.

have you tried this ?

Mathew Moxness comments:

hello, the error is a wordpress multi site and not gravity form multi page.


Arnav Joy answers:

this problem comes when you use , normal username instead of emails?

Mathew Moxness comments:

the problem happens on any input that I also assign to be the username. so if i choose email as the user name then it gives a validation error or if i choose company name it also gives a validation error.
