Re: Invalid JSON string with small file upload
 

I don't have an answer.  It has happened to me only once (2.4.5), using the file browser for a local file.  Unfortunately, I can't remember the file or its size but think I was trying to insert a small image into a label.  After restarting moodle, it went away.
