200pm update: I have disable the article level links for Elsevier so that only journal-level links will appear on Get It results. This is temporary until the problem with the article level links is fixed. Users will have to navigate to the article from the journal level links, but at least won’t be frustrated by broken article level links.
Elsevier has changed something in its openurl configuration causing ScienceDirect article-level links to stop working in Get It results. Journal level links are not affected. I will report when the problem is fixed.
