Login page redirect

Hello everyone,

– I have a big problem. On my site menu, when logged out, when I click on the Register button, it should normally redirect me to my registration form, but it redirects me to the login form, with a weird URL (https://mysite.org/login/?redirect_to=https%3A%2F%2Fmysite.org%2Fregister%2F).
– Similarly, when I click on “Contact us”, it should redirect me to my WPForms contact form, or it also redirects me to the login form, with a strange URL like above. Why do I have this problem?

Whatever I do, when logged out, it redirects me to my login page. “Register” and “Contact us” pages have no restrictions. Everyone can access these pages.
Could you help me please? I have to deploy soon and it is quite urgent.

Thank you in advance!
