Hi again,
I fixed the errors.
1. In the plugin file sm-gallery.php on line 72 remove the 3rd array element with the value ‘1’ from the 2nd parameter of add_action. So it changes from this:
add_action('get_footer', array($this, 'conditional_gallery_script_enqueue', 1));
… to this:
add_action('get_footer', array($this, 'conditional_gallery_script_enqueue'));
2. In the plugin file sm-gallery.php move line 20…
add_action( 'plugins_loaded', array ( 'sm_gallery_plugin', 'get_instance' ) );
… to below the definition of the class sm_gallery_plugin
That fixed all the errors for me. Perhaps a patch and a new version 1.1.19 is in order 🙂
I have had the same error on WP version 3.9.14. The error in this case is on line 470, but that equates to the same line in the do_action function.
It seems there is a do_action call that is not passing a valid callback function.
Any ideas? The error is pretty ugly next to such a great gallery…
