jsonKeywords plugin?

I’m cleaning up some html/php errors that OJS generates in my server log.

I’m receiving this error:
AH01071: Got error 'PHP message: Exception: Plugin jsonKeywords expected to inherit from PKP\\plugins\\Plugin, actual type NULL in /var/www/html/pkp/lib/pkp/classes/plugins/PluginRegistry.php

As of right now, I’m not finding any references to the jsonKeywords plugin, either in my installed code or the OJS database.

Hi @Steve_Michaels,

Would you mind noting your OJS version (e.g. 3.3.0-13)? Please include this in your posts as it assists with troubleshooting.
