 * Hi,
    I was attempting to review your plugin for WP Plugins A to Z and discovered
   an error with your plugin on activation. The first test site I tried it on it
   would not even install and the second one a clean uninstall of WordPress it had
   the following error you might want to have a look at it
 * ( ! ) Warning: in_array() expects parameter 2 to be array, boolean given in \
   wp-content\plugins\hidden-plugin\hidden-plugin.php on line 48
