I installed the latest version of this plugin onto my Moodle site (3.7.5) and after doing so it made my site unreachable. I was able to log into it but right after I logged in it displayed an exception error related to draw_navbuttons. I basically had to rename the H5P folder in order for my site to come back up. Has anyone else experienced this issue after installing this plugin? I didn't grab a screenshot because I was frantic to get the site back up and running.
