This one appears when a non-logged user manually tries to access one of my website pages with limited access, how can I modify its appeareance? I really can’t find a way.
There’s also the one that appears when a user registers on my site via custom form and tells him to verify his email, I understand I may fix this one by making my own sign up with javascript, but can I modify it without doing that?
Anyway the most important one I would like to edit is the one in the image. Thanks everyone.
