first of all I’m newbie to Icinga so I guess my issue is based on my low knowledge of the system. Using Icinga Web 2.6.2 with Director module installed. I added Business Process module 2.1.0 to module directory. After module was enabled menu item appears. When I click on it, i got error Class ‘ipl\Html\BaseHtmlElement’ not found . Looks like PHP cannot load ipl-html library. Can you please advice how to fix it?
