Hi Robert,
So logged in and updated everything following the instructions : https://webwork.maa.org/wiki/WeBWorK_2.15_Ubuntu_Server_20.04_LTS_Amazon_Machine_Image#Checking_for_and_Installing_Hotfixes
I tried to update OPL, using OPL-update, but that script is not there or command not found. Anyways rebooted my server and the issue still is there, apart from that course you created - I guess I will just band aid that as the solution to the courses I need.
Thanks again for the help.
