sit441 on "[Plugin: Contact Form 7] WP 3.6 doesn't work with CF7"

Hello,

Any of my sites with wp 3.6 (newest) does not work with CF7 (any version). Checked everything twice - any CF7 version doesnt send message (red error). But with WP 3.5.2 the newest CF7 works greatly at the same server and same mails.

Example may be found here: http://www.galgostudio.lt/kontaktai/

Any help would be nice :)
