   Hi, I just thought I would share this error message I received about your plugin. I don't think it's important, but I don't know enough to be sure.

   Basically, I'm using Wordpress MU, which has two different plugin folders. When I move a plugin from one folder to the other, wordpress thinks that the plugin has been deactivated, so it displays a little "Plugin Deactivated" message at the top of the Plugins page (wp-admin/plugins.php).

   With AmR iCal Events List enabled, I get this error message on top of the 'Plugin Deactivated' message:

   Warning: Cannot modify header information - headers already sent by (output started at /home/username/wpmu/wp-content/plugins/amr-ical-events-list/amr-ical-list-admin.php:481) in /home/username/wpmu/wp-includes/pluggable.php on line 865

   It doesn't happen with other plugins, so I just thought I would share it with you. Maybe there's something in your code that could be optimized or something.

   Anyway, great plugin!

   Hi I had a look and that line in the admin file is around the function that does the style which is does via wp_head, so that should be okay.

   I tried to replicate the situation by moving the plugin - got the deactivate message but not the headers message. The headers message usually means that something has already written to the page before it should have.

   You possibly don't have the latest version though as my line 481 is not an output line.

   Thanks for letting me know though - I'll keep an eye out!
