Uploading MapGuide package - Exception

Uploading MapGuide package - Exception

If you modify a MapGuide package make sure that you zip the correct files and folders afterwards.
I unzipped a MapGuide package, changed some values and zipped the folder but received the following error message when trying to upload the file:


Maestro error message:

MapGuide error message:

My mistake was to zip the top level folder - which I got when I unzipped the package. But you need to zip the content of the top level folder, not the top level folder itself.
