arsava / dokuwiki-plugin-metaheaders Goto Github PK

I've updated the host's installed PHP to 7.0, and dokuwiki to `Release 2017-02-19b "Frusterick Manners" and now I'm seeing this error repeated in the server logs:

[Sun Apr 30 16:38:24.538472 2017] [:error] PHP Warning:  Declaration of action_plugin_metaheaders::register(&$controller) should be compatible with DokuWiki_Action_Plugin::register(Doku_Event_Handler $controller) in /path/to/dokuwiki/lib/plugins/metaheaders/action.php on line 0

What needs to be changed for compatibility?

I've started getting this error at the top of my wiki's articles:

Warning: count(): Parameter must be an array or an object that implements Countable in /home/erinptah/public_html/leifandthorn/wiki/lib/plugins/metaheaders/action.php on line 62

Doesn't even have a CSS class that I could use to hide it from general view. The only way to get rid of it is disabling Metaheaders.

The wiki is here:

Also -- when the error message is there, a bunch of meta and link properties get moved to appear underneath it, i.e. inside the BODY tag. If I disable Metaheaders, or if you look at a non-article page like Recent Updates or Sitemap, they're back in HEAD where they belong.
