I didn´t get a mail notifying me of your reply…(!?)
The test page http://www.wollny-personal.de/cf7_mc_test/
with a copy of the CF7 form plus “[mathcaptcha mathcaptcha-<a_random_ID>]” shows
Fatal error: Class ‘WPCF7_Shortcode’ not found in /var/www/vhosts/wollny-personal.de/httpdocs/wp-content/plugins/wp-math-captcha/includes/math-captcha-cf7.php on line 20
– with or without activation of CF7 Dynamic Text Extension.
In line 20 mentioned above we find
$tag = new WPCF7_Shortcode($tag);
Sure you´ve registered the function? I didn´t find it.
CF7 only brings the class WPCF7_ShortcodeManager instead.
