Phil Eagles What to do if you upload eLearning to your LMS and it doesn’t work

Your eLearning is done. It’s ready to go. But then, you hit ‘upload’ and get the dreaded error message.

What To Do If You Upload Elearning To Your LMS And It Doesnt Work 17 10 18

This really is one of the most frustrating things you can come across as an eLearning developer or LMS administrator.

We’ve all been there, and unfortunately… it might happen again.

So, I’ve put together a list of go to options for troubleshooting your error message, from the simple to the more technical.

Here are some of the common issues I have experienced and how I resolved them:

File size error

Some LMS’s have a file size limit. If you find that your published output file size is slightly over the limit, you can usually reduce the file size by simply adjusting the quality settings in your eLearning authoring tool. If your tool does not have this feature you will have to scan through all images used and manually compress them with an image editor.

Tip - PNGs are fine to use for logos, graphics etc. but not photography. Due to their lossless compression they are very inefficient. Always use JPGs for any photographic images.

Videos can also take up a lot of space, so it might help to compress them with video editing software.

If all else fails, get in touch with your LMS supplier as they may be able to up the limit.

Duplicate manifest IDs

This is probably the most common issue we all face at least once. Duplicate manifest IDs usually occur when the eLearning is uploaded and then updated or replaced. Quite often it’s easy to forget when republishing to also update the manifest ID. Consequences other than failing to upload can be a partially updated eLearning which contains elements of both the new and old versions!

Tip - It’s good practice to change the manifest ID every time the eLearning is updated to prevent this happening.

eLearning published to Web rather than LMS

This is a really simple mistake to make. When you publish your eLearning, you are usually given two options: Web or LMS. If you publish to Web, critical LMS related files are not included. Consequently, the eLearning is rejected by the LMS.

LMS incompatible with output type

Most modern LMS’s are compatible with all major outputs. However, a small handful may not recognise the latest SCORM version or Tin Can API etc. Unless your eLearning specially needs to use the features of a particular version, it’s simple enough to republish with an older version. If this is not an option, you will have to look at a new LMS provider.

Tip - Always check the compatibility of your LMS prior to designing your eLearning, as this avoids any potential compatibility issues down the line.

Invalid characters in the published output zip

LMS’s can be notoriously fussy with particular characters, often rejecting anything that contains an unconventional character.

Tip - Stick with using typical ‘safe’ characters for your filenames. No Wingdings special characters!

If all else fails?

If all the above fail to work, I recommend uploading the course to SCORM Cloud This is usually my ‘one-stop shop’ to finding any issues with eLearning. The error and reporting tools are far more comprehensive than what LMS’s offer. If the eLearning successfully uploads on SCORM Cloud the next step is to contact your LMS provider for further diagnosis.
