Failed Ajax request or invalid JSON returned

[reaganch]

I get the error message "Failed Ajax request or invalid JSON returned" upon:

1. Cloning the repo to plugins/generic/disqus
2. Enabling the Disqus Plugin under Settings -> Website -> Plugins
3. Clicking on Disqus Plugin -> Settings

I'm running OJS v3.1.2. Any suggestions on what might be causing this?

Was just able to extract the relevant lines from the log file corresponding to this error, if it helps:

Thanks, the errors are there because the plugin does not support 3.1.2 yet. That version included some changes that affected all old plugin and I have not had the time to upgrade this yet. But will do so probably within the next week or so.

Thanks @ajnyga. Looking forward to adding this plugin to my website.
