this plugin is nice and simple, I really like it. However I found out, it's not working in Internet Explorer 9. It looks like its working normally, you can fill in the form, but the message is not sent in Explorer (it says it sent a message, but none is in email). In Opera and Firefox it works perfectly.
In IE it says it sent a message even if you fill wrong Captcha (in Opera or Firefox it works OK and doesn't let you send form until Captcha is correct).
I have plugin version 1.0 and WordPress 3.5.1 (I have tried 1.1, but php command for shortcode is not working in this version anymore - perhaps I need WP 3.5.2 or another bug?). Anybody has same problem?
Thanks for any info. Example here http://50950.w50.wedos.ws/subdom/en/ in footer.
