Course Presentation content upgrade stops with 404 after upgrading hundreds of items (WordPress H5P 1.17.9)
Hello,
I am using H5P on WordPress and I am trying to upgrade my existing H5P content to the latest library version.
My H5P libraries were upgraded successfully. After that, I started the "Upgrade content" process for existing content.
The upgrade works correctly for a large number of Course Presentation contents (more than 200 items are upgraded successfully).
However, after some time, the upgrade process stops and the browser console shows an XHR error:
