Doesn't work with Paid Membership Pro

Hi. I have exactly the same issue. Needed to restrict users from entering a space in their username during initial registration. Downloaded this plugin as it sounded perfect for my needs. Unfortunately it hasn’t stopped anyone from entering a space. I am also using Theme My Login 6.4.1 to keep users out of the backend during this process.

WordPress 4.3.1. Paid Memberships Pro 1.8.3.

Thanks

+1 would love see this resolved.

Hi

You can do this like that

it only accepts letters and numbers

regards

jQuery(document).ready( function () {

jQuery("#username").on("input", function(){
        var regexp = /[^a-zA-Z0-9]/g;
        if($(this).val().match(regexp)){
          $(this).val( $(this).val().replace(regexp,'') );
        }
      });
} );

Same.
