I'm expecting a bug with a specific web browser as Firefox. Internet Explorer & Chrome works fine.
When I try to submit the form, it doesn't send the e-mail, and the loading gif image keeps running. The debug got me this :
DATA IS NULL - var wpcf7ResponseOutput = jQuery(data.into).find('div.wpcf7-response-output');
contact-form-7/scripts.js?ver=2.2 (line 94)
line 94 :
Any idea ?
