We have successfully installed Learning Locker LRS on another server and followed the instructions from Opigno manual to connect to it. There is however no data appearing in Learning Locker. We also can not get LRS statistics to show up in Opigno (as shown in the screenshot in manual). what is the sure way of testing if any xAPI data is generated / sent to the Learning Locker? how to test the connection? does anybody offer services for testing / debugging this?
