Problem with WP-ContactForm 1.5.1 and Add an Image

It’s not just you, version 1.5.1 of WP-ContactForm breaks the media manager in WordPress.

I had the same problem. I deactivated all my plugins and then reactivated them one by one. WP-ContactForm is causing the problem with media manager. I think I’ll try to find another Contact Form plugin so that I don’t have to keep deactivating my contact form whenever I need to upload a photo.

In the beginning of wp-contactform.php there are some lines entitled “Grab some default user info, if available”. In order for Media Uploader to function properly, they should be moved to wpcf_callback function, right before the call of wpcf_check_input. Worked for me, hope this helps.

Thanks SergeyBiryukov for this fix. Works great for me.
For others looking at this later:

In wp-contactform.php, move this block of code (starting around line 13:

//Grab some default user info, if available (Submitted by Dan)
	$wpcf_auto_email = get_profile('user_email');
	$wpcf_auto_ID = get_profile('ID');
	$wpcf_auto_first_name = get_usermeta($wpcf_auto_ID, 'first_name');
	$wpcf_auto_last_name = get_usermeta($wpcf_auto_ID, 'last_name');
	$wpcf_auto_name = $wpcf_auto_first_name.' '.$wpcf_auto_last_name;
	if (empty($_POST['wpcf_email'])) {
		$_POST['wpcf_email'] = $wpcf_auto_email;
	}
	if (empty($_POST['wpcf_your_name'])) {
		$_POST['wpcf_your_name'] = $wpcf_auto_name;
	}

And move it, placing it just before this line (around line 137):
if(wpcf_check_input()) // If the input check returns true (ie. there has been a submission & input is ok)

After modify wp-contactform.php the images upload restart working.
