When trying to export a map series to PDF (separate pages or as single PDF) the output file(s) is 4kb in size and unreadable by PDF readers.
This is observed in 2.6.2 and 2.6.3
I found that by removing a .tif element (customer's logo) from the layout, the export is successful.
1) Why? A bug?
2) Is there a preferred image format that should be used instead of .tif?
