Just had an error while uploading a pic.
Seems to be in conflict with Contact Form 7.
No an emergency coz it works when CF7 is deactivated during my uploads. Would be nice to have a fix though.
Will be posting this on both NexrGEN Gallery and CF7's help forums.
Contact Form 7 Version 3.2
NextGEN Gallery Version 1.9.3
Wordpress Version 3.4
Fatal Error: Call to undefined function wpcf7_add_tag_generator() in .../plugins/contact-forms-7/modules/text.php on line 152
