Which folder on Panorama are you trying to publish to? And what error message are you seeing in the output tab of AutoQC?
Spaces in project or folder names should not cause a problem. The "Folder on Panorama" field expect the path to the folder on Panorama. So, for example, if this is my folder structure in the MacCoss project on PanoramaWeb:
|-- QC Folder
| -- Velos
To publish to the "Velos" folder the path I would enter is /MacCoss/QC Folder/Velos.
