SCORM package not loading

Every time I try to upload a scorm package I get the same error: The requested page "/opigno-scorm/ui/player/sco/" could not be found.' I found this issue on but my SCORM package is not structured in that way and that doesn't seem to be the problem, because colleagues have successfully uploaded the same SCORM package as I am trying (and it doesn't work with test SCORM packages either). Thanks!
