Hi @jmvezic, all,
I thought about this a bit more for the OJS 3 context, and tried the new OJS 3 Custom Header plugin to implement a cookie policy. It works - see Open Journal Systems Demonstration Journal. This cookie policy was derived from the following site/javascript: https://cookieconsent.insites.com/download/#. It comes with its own problem, namely the usage of the Cloudflare CDN, but this could be resolved using another similar cookie policy code snippet. Just a quick proof of concept; I’ll include some additional instructions for OJS/OMP 3 in the Guide once I have a better solution.
Cheers,
James
