upgrade from 2.1 to 2.7 database upgrade issues
I am trying to upgrade from 2.1 to 2.7 and I have followed the instructions for the 3 step and the extended. I copied everything over correctly, i launch the admin panel and I receive the message to upgrade the database. I click the up grade button, wait awhile and the only thig that comes up is the word press logo. Then I try to launch the admin panel again, and I receive the same note to upgrade. now if i press it again, i receive the following error.
WordPress database error Duplicate key name ‘comment_approved’ for query ALTER TABLE wp_comments ADD KEY comment_approved (comment_approved) made by wp_upgrade, make_db_current_silent, dbdelta
Is there something anyone can recommend? Should I try going to different version first, then up to 2.7?
Thanks for any help.
