Plugin version 1.5.0
Theme: NomNom - TwentyEleven child theme
Updating to latest version I get this on all admin pages.
Warning: Cannot modify header information - headers already sent by (output started at /home/******/public_html/tech/wp-content/plugins/ose-firewall/templates/menus/admin-menu.php:20) in /home/******/public_html/tech/wp-content/plugins/si-contact-form/wp-session/class-wp-session.php on line 92
This only appears on admin pages, nor the site front-end, so is probably not a serious conflict
Also messed up layout of Visitor Maps plugin "Whos Online" admin report.
Reverted to version 1.0.2 and no problems. I'll try the update again when I have time to fiddle with code...
Will also try the updated version on other sites that don't use FS Contact and Visitor Maps.
