I discovered that error is in upload field. When I deactivate this field, the form works fine. But, it’s not still a solution.
I’m using WordPress 3.4.2 and Contact Form 7 3.3.3, with the following add-ons:
Contact Form 7 – Dynamic Text Extension 1.0.4.2
Contact Form 7 Analytics by Found 1.0.1
I have already deactivated all the plugins and reversed to original theme, but the problem still happens.
Tks!
