I have just coded a form at:
http://bestbiztips.com/quickmedquote/welcome/request-a-quote-texas-residents/
When I fill out the form to test it, and enter my valid email address (one I have had for over 16 years), I get the hovered error message in a red box "Email address seems invalid."
So I tried my Yahoo email address. Same error.
What am I missing in the setup? Or is there something else going on? OR is it because I am using WordPress 2.8.5?
Thanks!
