While this works for OJS 3.1.2, the solution was (at least in my case; see: Block.tpl in OJS 3.1.2; keywordCloud plugin ) not backwards-compatible, i.e. i couldn’t get the “fixed” plugin working on both OJS 3.1.2 and earlier versions at the same time. This would in my opinion be a requirement for a bug fix though. Compatibility with OJS pre-3.1.2 can be achieved by symlinking ‘block.tpl’ into the plugin’s root folder but maybe there is a cleaner solution.
