1. Labels and or Manifest Summary PDF links give a 404 error or blank page
This usually is the result of either or both of the following:
- the content of the linksync extension have not been properly copied over to your server - in particular, the those contained in the 'media' directory.
- the permission on the linksync folders in the media directory aren't correct. The following folders should be set to 775 recursively:
/media/linksync/label/consignment/ /media/linksync/label/manifest/ /media/linksync/label/returnlabels/
After you check/correct the above to points, flush the Magento cache and try to create a new consignment and manifest and see if the PDF files save correctly.
