and here is my problem which i just found on my website.
After i complete the registration form and pressing submit button my browser doing nothing just stayed stuned to registration page the fields are clean but no registration occure and no new user been created.
If i disable Better WP Security Plugin my registration form works normaly as it should.
I tried to disable some other login plugins (Social login and Pie register) but it has no effect.
I tryed to rollback Better WP security down to 3.0 but it has no effect as well.
It's hard for to me to remember the dates but when i tuned everyting up (about 2 month ago, before 3.2.2) everything works fine.
So maby someone can give me an idea how to rule this.
