Calling non static method in statically.

[Karan1458]

Strict Standards: Non-static method gf_wysiwyg::get_base_path() should not be called statically in
***/plugins/gravity-forms-wysiwyg/gf_wysiwyg.php on line 49.

Quick fix : define('GRAVITY_WYSIWYG',plugin_dir_path(FILE));
On 49 line : require_once(GRAVITY_WYSIWYG . '/gf_wysiwyg_class.php');
