Downloading PDF from sagepub.com
I noticed that I can add article from sagepub.com into Zotero 4, but PDF was not downloaded, though it is free to download. Example:
http://journals.sagepub.com/doi/abs/10.1177/1754073910380971
http://journals.sagepub.com/doi/abs/10.1177/1754073910380971
You may need to restart Zotero and your browser after updating.
Any further problems let us know & thanks for reporting
