Even after running Zotero 5.0 since summer, Wiley translator still not working. Downloads citation info, but not the PDF. If you open the PDF, still cannot download it into Zotero. If you drag PDF icon into Zotero, still will not add the PDF. Only method which works (and defeats the ease of Zotero as a research manager), is to download the PDF into another folder, and then link to it from inside of Zotero. Wiley is a major science publisher, and many of my biology students are using articles from their journals. Thank you for re-looking into this translator problem.

@mstrahan: Moved to a new thread, so you can provide more details here.
