Incorrect file package - missing imsmanifest.xml or AICC structure
Hello,your zip package is not well-formed: https://docs.moodle.org/35/en/SCORM_FAQ#Incorrect_file_package_-_missing_imsmanifest.xml_or_AICC_structure.
Make sure you are publishing for SCORM and not just web. The imsmanifest.xml file should be included in the base zip package. If that is missing, it usually means you published to some other format.
