Hi, thanks for the replies.
I also thought that will be the template problem but it would be very troublesome to edit my template (because I got my template from woothemes & am not an expert in coding).
However, if I activate/use any other contact forms (besides Contact Form 7), there has no error in loading the template in any browsers.
But once I activate Contact Form 7, my site will only can load well in IE but not in FF & Chrome.
I like the simplicity of Contact Form 7 but why is it not compatible for all templates or all browsers like other contact forms?
