Wordpress. Validating h5p package failed.
I'm hosting with Pantheon and have installed the plugin fine.
When I try to add content via the hub, or upload manually I get this error:
Validating h5p package failed
I've tried several random content types and this happens every time.
I also can't upload my own.
I'm running Wordpress 4.8.2, and version 1.9.2 of the H5P plugin. I have ZipArchive and mbstring available, and am running PHP Version 7.0.23.
My upload limits are also ample.
I've attached my phpinfo() - this is a dev server in a none publi environment.
Any one have any advice?
