when you click on the link to the Demo of Health Science from this page (GitHub - pkp/healthSciences: An official theme for OJS 3.1.1+ designed for health science journals or any journal that wants a clean, modern appearance.), the link is not working. The link redirects to an error page which says: “Service Temporarily Unavailable. The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.”
I attach a couple of screenshots.
ps: I had found a similar situation with Immersion theme ( “Immersion Theme” Demo site not available)
