I just upgraded to the latest version of WordPress from WordPress 1.0.1 RC1.
I encountered this error when I clicked on the calender and archives:
Warning: Missing argument 2 for zeroise() in /home/mysitecom/public_html/weblog/wp-includes/functions-formatting.php on line 241
Any idea on how to troubleshoot this.
I just copied the latest files on to my server and ran the upgrade script.
