Contact Form does not work in Internet Explorer for IDN domains

Applicable to:

  • Plesk 11.x for Windows
  • Plesk 11.x for Linux
  • Web Presence Builder for Linux


A site with IDN domain name (e.g. домен.тлд) was published with Parallels Presence Builder . The following error occurs when I click the " Send " button in Contact Form with Internet Explorer web-browser:

Your message could not be sent due to an internal error. Please contact the website administrator by other means to notify about this issue.


Such behavior is considered to be a software issue. The fix will be included in future Parallels Plesk Panel updates released after 11.5.11. You can track it using the following ID:

Hotfix for Parallels Web Presence Builder 11.5.11

Fixed file /usr/local/sb/resources/site/modules/contact/send.php is attached .

To install the fix download the file to the server where Parallels Web Presence Builder is installed:

~# wget

Backup original file (just in case), replace it with the fixed file and correct permissions:

~# cp /usr/local/sb/resources/site/modules/contact/send.php /usr/local/sb/resources/site/modules/contact/send.php.bak
~# mv ./send.php /usr/local/sb/resources/site/modules/contact/send.php
~# chmod 644 /usr/local/sb/resources/site/modules/contact/send.php
~# chown root:root /usr/local/sb/resources/site/modules/contact/send.php

Remember to publish the site to apply the changes.

Note : the fix is applicable when PHP-5.3 or higher is installed on the server.
