Number of PHP warnings

Hi,

First of all thanks for the update, I’ve been using your plugin for a while now and it does exactly what I need.

That said, I’m working in a rather strict dev environment and once I upgraded to 4.0, I started seeing these:

Warning: array_diff(): Argument #2 is not an array in server_path\dev\wp-content\plugins\tinymce-advanced\tinymce-advanced.php on line 308

Warning: array_merge(): Argument #1 is not an array in server_path\dev\wp-content\plugins\tinymce-advanced\tinymce-advanced.php on line 309

Warning: array_diff(): Argument #2 is not an array in server_path\dev\wp-content\plugins\tinymce-advanced\tinymce-advanced.php on line 319

Warning: array_merge(): Argument #1 is not an array in server_path\dev\wp-content\plugins\tinymce-advanced\tinymce-advanced.php on line 320

Warning: implode(): Invalid arguments passed in server_path\dev\wp-content\plugins\advanced-custom-fields\core\controllers\input.php on line 94

Warning: implode(): Invalid arguments passed in server_path\dev\wp-content\plugins\advanced-custom-fields\core\controllers\input.php on line 94

Do you think it’s something reasonably easy to clean up?
