I put a widget on both sides. But if you just click the subscribe button (without entering an email), you will get the error popup I’m talking about.
It probably should also look for the period also, and not just the @ symbol.
Then if you put in a proper email, and no name, then you get a different popup, which appears at the top of the page in the center.
Right now I do use a different newsletter widget, but it doesn’t incorporate the user login subscribe button on the wordpress login page.
But if you go to http://personalstylist.ca/ on the right I have the one I currently use. If your email is wrong, it just pops up text in the same spot, then has a simple back button to go back. But I really do like your popup better, which means they don’t have to retype their email.
Hi, we are redesign totally the widget so probably all the problems will be solved with next version. Anyway, the first alert you see is created by your browser since the widget produce an HTML 5 form with the email field marked as “email”. That instruct the browser to check it and to show a message (that cannot be skinned). Probably on different browsers the alert will show differently or doesn’t show at all.
