   I just installed 2.1 on my own site, http://riverwriter.ca/wordcurrents/
   But when I post a comment, I get this error message, even though the comment posted correctly:

   Warning: in_array() [function.in-array]: Wrong datatype for second argument in /home/riverwri/public_html/wordcurrents/wp-content/plugins/subscribe-to-comments/subscribe-to-comments.php on line 434

   Warning: Cannot modify header information - headers already sent by (output started at /home/riverwri/public_html/wordcurrents/wp-content/plugins/subscribe-to-comments/subscribe-to-comments.php:434) in /home/riverwri/public_html/wordcurrents/wp-includes/pluggable.php on line 275

   I disabled a plugin I was running: "Subscribe to Comments 2.0.2", and that stopped the problem. I suspect it needs an update??

   Many plugins (and themes) need update to work with 2.1.
   Also, see the plugin compatibility list fro mroe details:
