Moodle 3.7 Fordson v3.7 release 1.2.2 2019111010
When I try to change to this them, I get the error "Invalid JSON String'.
The message has on "OK" button, but that does nothing. There is a small "x" in the upper right-hand corner, that will eventually close the message, if I click it about 20 times.
Any help appreciated.
