Hello, @Siva,
Yeah, that might affect Logins and that issue seems to be independent of our theme, could you please check it once by activating the default WordPress Theme like Twenty Twenty Three, just to make it sure that the issue is from our theme or not?
If the issue will still persist with the default WordPress theme as well, then it will make sure that the issue is not because of our theme and in that case you have to contact the WordPress support because once it will be fixed with the default WordPress theme, it will automatically work fine with our theme as well.
Regards 8Themes Team.
