 * Thought I’d try this plugin out but I get this error when I set up my API key:
 * options.php was called with an argument that is deprecated since version 2.7!
   The vpxb_username setting is unregistered. Unregistered settings are deprecated.
   See [https://codex.wordpress.org/Settings_API](https://codex.wordpress.org/Settings_API)
 * Warning: Cannot modify header information – headers already sent by (output started
   at /home/mysite/public_html/wp-includes/functions.php:3570) in /home/mysite/public_html/
   wp-includes/pluggable.php on line 1207
 * Just wanted to see if there was a fix for this…
 * Thanks! Love the concept of this plugin, hopefully can get it to work 🙂
