Actually using Version 2.8.5
I am getting the following error message after entering or editing most pages, post or settings.
"Warning: Cannot modify header information - headers already sent by (output started at /home8/jltaxplu/public_html/wp-content/plugins/wordpress-blog-stat/stat.php:37) in /home8/jltaxplu/public_html/wp-includes/pluggable.php on line 865"
However, the changes/edits are made. The error message just creates an extra step to remove it from the screen before you can continue.
