Use of undefined constant LANG_ERROR_GROUP

I am using ClickHeat plugin for piwik, and got this:

WARNING: /path/to/piwik_deploy/www/piwik/plugins/ClickHeat/libs/generate.php(65): Notice - Use of undefined constant LANG_ERROR_GROUP - assumed ‘LANG_ERROR_GROUP’ - Piwik 2.14.1 - Please report this message in the Piwik forums: http://forum.piwik.org (please do a search first as it might have been reported already)

Hi there,

please report the issue in the plugins’ issue tracker itself, to be sure the plugin developer will be notified :slight_smile:
