 * I’m using php 5.4, and I’m getting this small error.
 * Only variables should be assigned by reference

 * I’m thinking just remove the ‘&’ in front of the function on that line.
 * From
 * `$parent = &get_post($parent);`
 * to
 * `$parent = get_post($parent);`

 * Removed on next version, pushing later today.
