thanks for your answer!
it’s very interesting. I checked twice everything but it does not work. I use the latest from everything (WP, WPCF7, etc.) if it works for everbody with all the latest applications and there are no complaints, then it’s possibly that I do something wrong but I couldn’t find it out, until now. If you have some time, could you please test CF7 with the latest apps? would be nice! thanks!
