Hi
The message 'The file you are trying to upload might be too large.' occurs in h5peditor-file-uploader.js when the file contents fails JSON.parse.
This could be for a number of reasons, including a corrupt file or indeed a file that is too large.
I spent ages looking at what was restricting the file size before I found this out and discovered the real cause of the issue that I faced.
Could this message be made more generic and reference JSON?
Regards Rory
