Chamilo LMS

When adding learnpath items through drag and drop, I get the following warnings:

These are warning messages logged into my error_log but not seen on screen. I guess this is something that has been overlooked in the JS element to create an item and it should be easily fix-able.
Nice feature, by the way.
