Can you please share an example article? We review these errors on a case by case basis.
I am doing a research project so I come across these regularly. Is there a place to quickly report these?
It looks like the button (at least for this reference) is now appearing but when I press it I get a printout of a PubMed search return:
doi: 10.1016/j.coph.2007.03.002. Epub 2007 May 1.

Thanks for sharing this. There's no built-in reporting tool. You can email our tech support at email@example.com if you prefer that over public posts.
I can confirm that this article is not open access, at least that's indicated on Unpaywall's open-access index. The file that's served by the plugin is served because of an error. I have now pushed this to the engineer's backlog.
It seems to be what is indexed by Google scholar: https://scholar.google.com/scholar?hl=en&as_sdt=0%2C39&q=Natural+products+as+a+gold+mine+for+arthritis+treatment&btnG=
