Get this error:
Warning: Cannot modify header information - headers already sent by (output started at /home/.chad/mshearer/www.netexperienced.com/cms/wp-content/themes/plainscape.1.0/plainscape/page.php:10) in /home/.chad/mshearer/www.netexperienced.com/cms/wp-includes/pluggable.php on line 850
I disable the Reg Level Plugin and this error disappears. I tried Reg Level on a different site and got a similar error (different location in the code, however).
I tried going into the plugin to look for whitespaces, as well as the place in the code highlighted by the warning, but no luck.
