I suspect the issue has to do with the load order of the plugins / filters. The plugin that has the the apply_filters() call (inside of CTALoadExtensions) is running after the plugin that has the add_filter() call. Try putting add_filter() inside of a function that is tied to plugins_loaded.
You don’t pass more than argument to that filter, so any callback expecting more than one will not get it. The core calls this filter always like this: $title = apply_filters( ‘widget_title’, empty($instance[‘title’]) ? ” : $instance[‘title’], $instance, $this->id_base ); But you are passing just $instance[‘title’]. Add the missing parameters, and the error will vanish. … Read more

Make use of custom parameter, lets call it wpse__current_year, which will accept two values, true (includes current year) and false (excludes current year).

the_content filter is as good as other filters are. The issue is that it is supposed to be run inside a loop with the glogal $post correctly set to current post in the loop. So, you could do something like this (not tested, just written here as example): $content_before_category = get_theme_mod( ‘content_before_category’, false ); if … Read more
