I just tried to upgrade from WP 2.07 to 2.1. I have done earlier upgrades without a problem. I am receiving the following error when I try to go to http://www.gml-law.com/wp-admin/upgrade.php:
Fatal error: Call to undefined function: add_filter() in /home/fhlinux182/g/gml-law.com/user/htdocs/wp-includes/default-filters.php on line 4
I have now downloaded and installed version 2.1 twice and continue to receive this error.
I have been here (http://wordpress.org/support/topic/68707?replies=4) and it is not helpful to me. Likewise, this page (http://codex.wordpress.org/Changing_File_Permissions) is not helpful.
Can someone please give me a hand as this is my work site (it’s just me) and I’d like to get this working ASAP. If it is a permissions issue (as I suspect it is and just cannot figure out), can you give me specific file names and permission numbers?
Thank you in advance.
