I've a fresh install of wordpress with no other plugins activated. Hosting is https://www.blacknight.com/medius-hosting.html

I'm getting the following error when I try to run the installer.

Fatal error: Uncaught exception 'LogicException' with message 'Passed array does not specify an existing static method (class 'HTMLPurifier_Bootstrap' not found)' 
in /var/www/vhosts/37/253640/webspace/httpdocs/XXXXXXXXXXXXXXX/wp-content/plugins/civicrm/civicrm/CRM/Core/ClassLoader.php:122

Any idea why this error is occurring? Looked for a solution but could not find anything.



  • Can you clarify what instructions you followed for installation? – petednz - fuzion Dec 3 '15 at 17:50
  • Simply activated plugin and went to Settings -> CiviCRM Installer wp-admin/options-general.php?page=civicrm-install where error above shows – user3045777 Dec 3 '15 at 18:27
  • not clear - did you follow steps outlined eg wiki.civicrm.org/confluence/display/CRMDOC/… – petednz - fuzion Dec 3 '15 at 22:00
  • Yes I followed installation (I've installed before with no issues). I get this error on Step 5. Enable CiviCRM plugin and run installer (wp-admin/options-general.php?page=civicrm-install) – user3045777 Dec 4 '15 at 15:14
