Hi!
I just tested it and it seems to be working fine. Please open the file includes/settings.php and go to line 64 (sanitize function). This is what you should see:
// Save the IDs
$fn = 'list_of_feat_post_ids';
$new_input[$fn] = array();
...
if ( ... ) {
if ( ... )
...
elseif ( ... )
... json_decode ...
}
If you add the following piece of code right after the previous snippet:
echo '<pre>';
print_r( $new_input['list_of_feat_post_ids'] );
echo '</pre>';
die();
After doing that, if you try to edit your featured posts, WordPress will ignore your request and show a list of the IDs of your selected posts:
Array
(
[0] => 27
[1] => 361
[2] => 47
)
Does the list still include the post you just removed?
