Dear Sirs:

I just installed WP3 MULTISITE, and decided to use ANTISNEWS 1.9 Template as a test prior to buy your premium version. After installing and ANTISNEWS selected, when hit MENU under Aspect we get the following errors:

Warning: Cannot modify header information – headers already sent by (output started at /home/user/public_html/website.com/wp-admin/nav-menus.php:453) in /home/user/public_html/website.com/wp-includes/functions.php on line 830

What this mena ? How to fix this ?

After we install free Antisnews 1.9 version and adquiere Antisnews 1 Premium, can we simple upgrade to the premium version ? How to upgrade ? Will we loss all our work on free version ?

What's differrences between both versions ?

Hope to hear from you soon.
