I just upgraded to WP 3.4, and contact form 7.3.2. It seemed to work at first, but when uploading pictures with the NextGEn gallery, I got this:
ERROR: 21-06-2012-hq-01.jpg : Fatal error: Call to undefined function wpcf7_add_tag_generator() in /var/www/raymondhaaken.nl/_/htdocs/blog/wp-content/plugins/contact-form-7.3.2/modules/text.php on line 152
And I can't upload any pictures. So I reverted back to contact form 184.108.40.206, and now things work well again.
