I just upgraded my site http://www.forexnode.com to the wordpress version 2.9
First I tried to upgrade it thorough the control panel but it didnt work.
So I upgraded manually by replacing the old files with the new ones.
but when i try to reach a sub page like http://www.forexnode.com/brokers/
it works normally.
I am able to access the wp-admin
and have disabled all the redirection plugins like www. preference.
Kindly provide your support as soon as possible.
