Error when altering a library
First let me walk you through what happened. I downloaded the interactive video library and used it for wordpress and it worked just fine. In attempts to add on to it, I first decided to try creating a simple H5P library, such as the Hello World! tutorial. After creating it following the step by step instructions, it allowed me to put the library on my website, but when I tried to create with type "Greeting Card" it just gave me a blank page. Then I realized there were updated versions of it of patch 1.3, and so I copied the files and it worked.
