Hi, I installed the plugin on moodle 3.3.1 but I can not set the status. I
received this error error/moodle/missing param. how can I fix it?
you have not provided enough information for us to offer any help.
Please turn "display errors" and set "developer level" in your debugging settings, then provide a screenshot of what is displayed.
sorry for the little information given. Attached to the screenshot of the error
Thanks - that looks like a bug that occurs when "Allow students to record own attendance" is disabled.
I've just pushed a fix into the github repo for this - thanks for the report!
