Hi everyone, I recently migrated my moodle site from version 2.4.6 to 3.3.3.
The issue is that in version 2.4.6 I was able to connect to my site using the official moodle mobile app for Android (the app version is 3.4.0 ). But now with moodle version 3.3.3 I can't connect to my site, because when I enter my moodle site URL and press connect I get the error "Coding error detected, it must be fixed by a programmer: Invalid json in request: no error". I'm using php 5.6.32. I've read forum messages with similar problems, but solutions given don't fix it.
Well, If someone could help me I would appreciate it.
