Installation and server related problems

I recently set up a Drupal server with H5P.  I downloaded a few interactions from my H5P.org account and was able to upload it successfully to my H5P server.  But when download interactions from this person and try to upload them to my server I receive an error message.  Any ideas on why the server accepts some uploads but not this file?  

Also, when it errors, H5P refers to an "error log"?  where can I find that log?

Hi,

I'm a non-technical user tinkering with H5P and happy with the results on my WP site; elements work really well and they display correctly on all screen sizes.

Do H5P can be used in mauthor-like educational comercial platforms?
