Warning: in_array() expects parameter 2 to be array…

I keep getting this error on my page. I looked online but the fix to it doesn’t work. It just gives me a second error.

I keep getting this warning

Warning: in_array() expects parameter 2 to be array, string given in /home/creadores2015/public_html/pr/wp-content/plugins/adminimize/adminimize.php on line 901

The line it’s referring to says

if ( isset( $mw_adminimize_menu ) && in_array( $item[ 2 ], $mw_adminimize_menu ) ) {
					unset( $menu[ $index ] );

The fix I found online said to change “in_array” to “is_array” but that won’t work.
