# Deprecated functionality error.

 * I am getting the following PHP error on all the WordPress SEO admin pages:
 * Deprecated: Assigning the return value of new by reference is deprecated in /
   Library/WebServer/Documents/LawMyWay/wp-includes/class-simplepie.php on line 
   14904
 * Of course the line number at the end changes with the approximately 122 iterations
   of this error message. They start with line number 738 and end with 14904. I 
   have not dug through them to determine if there is a pattern to the numbers.
 * Can you help?
 * Also, if I have installed Headspace2, can I delete it if I am using your plugin?
 * Thank you.

 * Hi Lewis,
 * as far as I can tell, this is in WP core or another plugin and not in my plugin,
   as I do not pass a variable by reference in my RSS code…
