I have a problem with the creation of a new user (author) on WordPress.
When the new user tried to log in in the admin the site went down and at the moment I can not even access the admin.
I've installed WP via 1and1.it, where the site is hosted (https://techplaza.it).
Have you ever experienced similar problems? This has already happened to me, for example when I tried to access the dashboard section of the app for iOS (iPhone and iPad). In that case site was ok after 20/30 min.
