Tried accessing the ClickHeat plugin, and was presented with an error:
Fatal error: Class 'Piwik_ClickHeat_Controller' not found in /home/twitco/public_html/analytics/plugins/ClickHeat/libs/layout.php on line 18
The following error just broke Piwik (v2.13.1):
Class 'Piwik_ClickHeat_Controller' not found
in
/home/twitco/public_html/analytics/plugins/ClickHeat/libs/layout.php line 18
Now on subsequent pages I receive the following error:
WARNING: /home/twitco/public_html/analytics/plugins/ClickHeat/libs/cleaner.php(157): Notice - Use of undefined constant LANG_CLEANER_RUN - assumed 'LANG_CLEANER_RUN' - Piwik 2.13.1 - Please report this message in the Piwik forums: http://forum.piwik.org (please do a search first as it might have been reported already)
I’ve not found this issue already reported on forums or GitHub. The ClickHeat map would not generate.
