Please tell me how to edit the text on the registration page? When registering on a wiki, users drive spaces into logins or their email with the "@" sign, which will cause a login error and is replaced by "_" , write their real name in Cyrillic.
Can I change the text on the registration page and write whatever they do? If so, how?
And even better if it can be implemented so that an incorrect login would cause a pop-up window with an error
Thanks in advance!
