We have installed the latest version Ironwood, but we are struggling to enable the xblock plugin. We have installed the raccoongang xblock from https://github.com/raccoongang/edx_xblock_scorm, but the xblock option doesn’t show up for our courses. We have followed the instructions about adding scormxblock to the advanced module list, and making sure we are accessing only through https. There were no errors during install. Any help is appreciated.
