While working in Web Presence Builder: "Unable to connect to Parallels Web Presence Builder Server. Please contact your administrator"

Applicable to:

  • Plesk 12.5 for Linux
  • Web Presence Builder 12.0 for Linux
  • Plesk 12.0 for Windows
  • Plesk 12.0 for Linux

Symptoms

While working in  Web Presence Builder (WPB) and attempting to save a site snapshot or add a widget, WPB Presence Builder returns an error:

Unable to connect to Parallels Web Presence Builder Server. Please contact your administrator.

An error is also shown in the /var/log/sw-cp-server/error_log log file:

FastCGI-stderr: PHP Fatal error:  Allowed memory size of 134217728 bytes exhausted (tried to allocate 42223355 bytes) in /usr/local/sb/include/SB/Site/Snapshot.php on line 197

Cause

WPB needs more memory to save the site snapshot than is currently allowed by the control panel web server configuration.

Resolution

  1. Back up the file /usr/local/psa/admin/conf/php.ini :

    cp /usr/local/psa/admin/conf/php.ini /usr/local/psa/admin/conf/php.ini_backup
  2. Open the file for editing and increase the memory_limit value (for example, from 128M to 256M ):

    memory_limit = 256M
  3. Save the file and restart the psa service:

    /etc/init.d/psa restart
