WordPress.org has finalized WordPress 3.4 and is planning on pushing out the update early next week.
I have tested and confirmed that both the Easy Sign Up plugin (and extras) and the Easy Heads Up Bar are working great in WordPress 3.4 Release Candidate 2.
So that is one less thing for my users to worry about.
I do suggest that you back up your website’s theme, uploads, plugin files and your database before any major update.
If you need help with this we offer a WordPress no Stress back up and upgrade service, just contact me with your details and we’ll get you upgraded the right way!
