I have a Dupal core 7.59 instance with H5P 7.x-1.35 installed.
When I attempt to update the content types via "Interactive Content" tab I get the following error.

Validating h5p package failed.

The file you uploaded is not a valid HTML5 Package (We are unable to unzip it) Get help

Any idea how I can fix it?

Hi Robert,

Can you please check your browser console for errors and any PHP errors.


My Problem was that the sites/default/files/h5p folder was lacking the right to write a file to.  When the downloaded file is not written to the filesystem the drupal 7 h5p module gives the "not a h5p file" error. 



I'm downloading H5P files from, then extracting the ZIP,  changing one CSS declaration, recompiling the ZIP, renaming to .h5p and uploading to my  No matter what I do (or how LITTLE I do), I get two errors:
What am I doing wrong? Thanks

Hi ArchonKen,

It's possible that you may be zipping the files the wrong way. Could you please check if you zipped the folder (won't work) or all the files (should work)?

As BV52 mentioned, your ".h5p" file is really not an ".h5p" file, since it contains a css_test folder. It should contain the following files/folders in the "root" of the H5P file:

  • content
  • Drop-1.0
  • FontAwesome-4.5
  • H5P.DragText-1.7
  • H5PEditor.RangeList-1.0
  • H5PEditor.TableList-1.0
  • H5P.FontIcons-1.0
  • H5P.JoubelUI-1.3
  • h5p.json
  • H5P.Question-1.4
  • H5P.Transition-1.0
  • jQuery.ui-1.10
  • Tether-1.0

You could also have a look at the H5P spec

It is the way the file is compressing.  Your file contained empty file paths.

For OS X and Linux run this command in terminal to remove extra files and empty directory paths.

zip -r -D -X css_test.h5p *

-D   do not add directory entries

-X   eXclude eXtra file attributes

To verify and compare the h5p files type:

zipinfo css_test.h5p
