 * Hello everybody.
 * I have an installation of wordpress with buddypress.
    When I activate the Buddypres
   docs plugin, I get this message in the desk:
 * Warning: in_array() expects parameter 2 to be array, null given in **WEBroot**/
   wp-content/plugins/ps-taxonomy-expander/ps-taxonomy-expander.php on line 752 
   Warning: in_array() expects parameter 2 to be array, null given in **WEBroot**/
   wp-content/plugins/ps-taxonomy-expander/ps-taxonomy-expander.php on line 752
 * Can I have any suggestion or solution for me?
 * Thanks!

 * This seems related to a problem of compatibility between BUDDYPRESSDOCS and WORDPRESS,
   although I have none at all clear.
    Please, Does someone have the solution?

 * From the error message, I would suggest disabling the plugin ‘ps-taxonomy-expander’.

 * It works! Thanks. I guess that ps-taxonomy was the guilty.
    Thanks Boone

 * Awesome! You may want to contact the author of that plugin, and let me know if
   he or she reports that there’s something that can be done in BP Docs to help.
