Not a Problem


After the installation of Kopernio extension, the PubMed homepage could not be opened anyway. Even I tried the uninstall/reinstall the Kopernio extension, restart the Mac, the Pubmed homepage died. Any comment or solution?

Dear Qian, Thank you for taking the time to report this.

I couldn't reproduce this error on my end - I can open PubMed without a problem. I found reports that the PubMed platform was inaccessible for a short time over the weekend. Let me know if the issue still persists on your end.
