With Contact Form 7 (V 2.1.2) activated, the Tag-Generator from Kimili Flash Embed (also V 2.1.2) won't show up. The overlay is blank and displays an error message:
Fatal error: Cannot redeclare wpcf7_add_tag_generator() in [domain]\wp-content\plugins\contact-form-7\includes\taggenerator.php on line 3
I think this has been a problem in previous versions, but somehow it seems to persist.
When I disable Contact Form 7, everything works fine.
