I have enabled the debug.log in my wp-content and found the following error:
[19-Dec-2010 06:48:15] PHP Notice: Trying to get property of non-object in /home/[domain]/public_html/wp-includes/query.php on line 327
I am having a constant 404 error when publishing and this is really annoying. Turning mod_security off does not help, nor any other action/advice I've applied following the instructions in the WP forums.
If there is any connection between the two of them would be good to know.
Also, any advice is appreciated.
