 * Hi guys,
 * I know next to nothing about CSS, so please be gentle and very precise with answers!
 * My Page and Post entries show this error in the dashboard:
    **Warning: in_array()
   expects parameter 2 to be array, boolean given in —-/wp-content/themes/shiword/
   lib/slider.php on line 33**
 * along with
 * **Warning: in_array() expects parameter 2 to be array, boolean given in —-/wp-
   content/themes/shiword/lib/slider.php on line 47**
 * The site I am working with is [http://www.mai-con.net/test/](http://www.mai-con.net/test/)
 * Here is the code in that file.
 *     ```
