"Error, unable to load libraries" when editing H5P in WordPress 5.2.4
I have created several H5P projects in my WordPress multisite using the H5P plugin. I am getting a "Error, unable to load libraries" message whenever I try to edit one of my H5P projects or look at my "Libraries". I run a sandbox site with the H5P plugin on the same server and do not get the error message. I am running WordPress 5.2.4, the H5P plugin is version 1.14.1, and my site's PHP version is 7.2.23.
