We're experiencing an issue with Parallels Web Presence Builder 11.0, with the "Contact Form" module inside of WPB. The customers are not receiving email when the form is filled. Also Captcha does not work.


"Contact From" emails are sent via PHP function mail from the server where to the site is published (where the domain is located).

  1. Server "host" where to the site is published is out of free disc space:

    [root@host ~]# df
    Filesystem           1K-blocks      Used Available Use% Mounted on
    /dev/sda1             45067080  43826804         0 100% /
  2. PHP functions "exec", "popen", "pclose" and others are disabled in configuration file on the publishing server "host":

    [root@host ~]# grep disable /etc/php.ini
    disable_functions = system,apache_note,apache_setenv,closelog,debugger_off,openlog,syslog,popen,pclose,exec
  3. Outdated Captcha of Parallels Web Presence Builder 11.0.


  1. Release some or add more disc space to the publishing server "host".
  2. Enable PHP functions "exec", "popen", "pclose" at least, test other functions.
  3. Upgrade your edition of Parallels Web Presence Builder to version 11.5 that works with reCAPTCHA.
