Hi @achristian,
Hmm, I couldn’t reproduce that mash-up behavior on my OJS 3.1.1-4 installation… The 3.0.0 release of the plugin should be compatible with OJS 3.1.1-x, so I’d suggest installing it from Releases · ojsde/shariff · GitHub by downloading it to your machine and then uploading it into the plugins area as a .tar.gz package. As for general capabilities, I’d suggest asking the author of that plugin if you have any questions.
Regards,
