[Plugin: WP-EMail] Save options redirects to root site (in WP 3.0 multisite)

I was unable to find out what conflict was causing this problem.

I had the same problem, it seems this plugin is not ready for wp-multisite;)

But I think you can fix it like this:
– open the file email-options.php in the wp-email folder
– go to line 159 and change this code:
<form method=”post” action=”<?php echo $_SERVER[‘PHP_SELF’]; ?>?page=<?php echo plugin_basename(__FILE__); ?>”>
into this:
<form method=”post” >

that worked for me…

To fix that and front end 404 error when clicking on email button, please find an updated plugin here :
