Adding: add_filter( ‘wpcf7_load_js’, ‘__return_false’ ); to the functions.php solves problem. But then what is the point, those are CF7 necessary scripts.
It is worth for developers to take a look into this problem. Both plugins are installed on plenty of websites. I will repeat most important points:
– Theme makes no problem.
– Other plugins make no conflict (I tested with only CF7 and ACF PRO activated on Page.)
– With ACF PRO deactivated CF7 works and send mails.
– Or better to say, with CF7 JS scripts deactivated.
– Uoploaded again source files of latest WP, CF7, ACF PRO.
– wp-config.php and .htaccess files are OK.
– No cache remains folders around.
– mu-plugins folder clear.
– SSL certificate, seems as, working OK.
– Definitely not problem with mod_security or server firewall (or ?)
I do not know what plugin is a bit away from WP coding practices. But the fact is ACF PRO is influencing CF7 form functionality, not the other way around. CF7 makes no problems for ACF PRO. Not visible anyway.
