 * Hi there,
 * First of all, thanks for the great plugin.
 * I am using WP 3.5.1 with 2012 template no other plugins but wp-members and wp-
   SMTP. I have de-activated wp-SMTP which makes no difference to the error.
 * Here’s my problem: A new user registers on my site, I get a notification. I go
   to the user list, click “activate”, and then get the following error message:
 * Warning: stripos() [function.stripos]: needle is not a string or an integer in[
   site-root]/wp-includes/functions.php on line 658
 * Warning: stripos() [function.stripos]: needle is not a string or an integer in[
   site-root]/wp-includes/functions.php on line 661
 * Warning: Cannot modify header information – headers already sent by (output started
   at [site-root]/wp-includes/functions.php:658) in [site-root]/wp-includes/pluggable.
   php on line 876
 * I have tried other suggestions such as making sure there is no space above and
   below php tags in functions.php, but that hasn’t helped. The thing is, the activation
   email is sent with the password and lets them log in.
 * The activation check box inside the user’s profile works fine and doesn’t throw
   the error.
 * Has anyone else run into this problem and found a solution? It seemed to work
   fine at first, but then this error suddenly started happening…
 * Thanks in advance for any help.

 * I’m not using WPMU.
 * However, It is one of 2 wp installations on the same domain. The installation
   mentioned above is in a subfolder of another installation of wp.
