Here is the error message:
Error: File: ../files/appLms/scorm/11836_15_1461863779_Fair Housing Ch 1.zip_content/imsmanifest.xml not found 
1) upload size is managed by the server configuration, not by the lms, just like Alberto said here... viewtopic.php?f=2&t=12489
2) error: I am fairly sure that you zipped your scorm including the folder where your contents have been published. It's something already documented on this forum, as many users make the same mistake.
When zipping, if your authoring tool doesn't do it automatically, just zip the published output. Not the whole folder where the output is included.
When you upload, the system automatically unzips your package and immediately looks for the imsmanifest.xml file. If it's inside a further folder, it doesn't find it and gives you that error.
