Hello,
I have activated the following Plugins:
– Page Builder by SiteOrigin 2.5.2
– Learnpress 2.1.6.1
– Standard WordPress Theme (Twenty Seventeen)
If I use the Page Builder on lp_course (“Course”), then the Curriculum will not be saved. If you put in a title and a lesson, then press on “Save” the curriculum will not be saved and the complete curriculum will be deleted.
I tested with Page Builder by SiteOrigin Version 2.4.25 and their all works fine.
Hopefully you find the bug :)
