Blank page appears, when trying to create an HTML signature in Roundcube.

In the '/var/log/plesk-roundcube/errors' the following error appears:

    [29-Apr-2015 19:35:31] PHP Fatal error: Class 'rcube_washtml' not found in /usr/share/psa-roundcube/program/steps/settings/ on line 192


This is Plesk internal issue #PPPM-2773, which has been fixed in Plesk 12.0.8.


  1. Copy attached file into '/usr/share/psa-roundcube/program/lib/'

  2. Add the following line to the top of '/usr/share/psa-roundcube/program/steps/settings/' file:

    require_once 'program/lib/rcube_washtml.php';
