   Hello,

   Since I updated to 2.7.1 I have no longer been able to post any source code without triggering an error; except by disabling the syntax highlighting plugin I use (Syntaxhighlighter). I tried other similar plugins to see if it was a plugin error but not even the 2-day-ago updated Syntaxhighlighter Plus worked.

   The error appears when attempting to publish/save/preview any post containing [code] or [sourcecode] tags and this appears:
   
   Warning: htmlspecialchars_decode() expects parameter 1 to be string, NULL given in /home/iniciat/public_html/main/wp-includes/compat.php on line 105

   Warning: Cannot modify header information - headers already sent by (output started at /home/iniciat/public_html/main/wp-includes/compat.php:105) in /home/iniciat/public_html/main/wp-includes/pluggable.php on line 850

   Any help will be very appreciated,

   thanks

   Thanks for pointing out a possible solution but the compat.php file is untouched from the original. I followed the steps in the link you posted to make sure there are no spaces or other code outside the PHP, but the error persists.

   Can confirm, exact the same behavior here.
   Wordpress 2.7.1, Syntaxhighlighter 1.1.2

   as deactivating the plugin helps, it doesn't seem to be a problem of WP but of Syntaxhighlighter :(
