I have K2 version 2.9.x installed now with a registration page. After filling out the page on the site with their name, username, email, password, etc and click 'register', the page simply reloads and resets with the fields blank and registration is not completed. I enable the "Enable K2 User Profile" option to add additional fields in the register form. But if I disable this option "Enable K2 User Profile" registration working fine but it disables the k2 extra fields from register page.
Can you please help me out what is the issue.
