 Warning: count(): Parameter must be an array or an object that implements
 Countable in wp-includes/meta.php on line 210

 This error prevents any posts from being updated. It seems it is erroring
 because $old_value may not always be an array.

 This is the original line that causes errors:

 {{{if ( count( $old_value ) == 1 ) {}}}


 The fix checks to see if $old_value is an object or array:

 {{{if ( (is_array($old_value) || is_object($old_value)) && count(
 $old_value ) == 1 ) {}}}




 After fix is implemented, everything seems to work fine.
