 * When someone registers (using the pie-register plugin), they get the following
   error messages:
    `Warning: in_array() [function.in-array]: Wrong datatype for
   second argument in /home/p9575r65/public_html/site/wp-content/plugins/pie-register/
   pie-register.php on line 810`
 * `Warning: in_array() [function.in-array]: Wrong datatype for second argument 
   in /home/p9575r65/public_html/site/wp-content/plugins/pie-register/pie-register.
   php on line 815`
 * `Warning: Cannot modify header information - headers already sent by (output 
   started at /home/p9575r65/public_html/site/wp-content/plugins/pie-register/pie-
   register.php:810) in /home/p9575r65/public_html/site/wp-includes/pluggable.php
   on line 934`
 * The registration actually works, but I’m not sure the registrant will recognize
   that it has happened, given the error code.
 * I’m thinking of fixing this by reverting to a previous version of pie-register.
   I presume I would simply delete the files under that folder in PlugIns and replace
   them with the previous ones.
 * Does this make sense?

 * Sorry I can’t be of much help on this (it’s from eleven months ago). Apparently
   I gave up on Pie-register and now just use Meta; which works fine.
