The issue may be related to how the SCORM package was zipped, particularly if it was created on a Mac. When a SCORM package is zipped on a Mac, an extra hidden folder (e.g., _MacOSX) may be added to the zip structure. This additional folder can interfere with how the platform reads and accesses the content.
When uploaded without this extra layer, the SCORM package appears and functions as expected.
To resolve this issue:
- Unzip your SCORM package and check if there are any extra folders at the top level (e.g., _MacOSX).
- Ensure the core "Content" folder and files are directly accessible without any additional layers.
- Compress (zip) only the required content and re-upload the newly zipped file.
Alternatively, saving and zipping the file on a PC instead of a Mac tends to work as expected. You can also compare the folder structure against a successful SCORM upload to verify the correct format.
