I can't upgrade to 3.5.1.
When I attempt to automatically upgrade, I get the following message:
Fatal error: Cannot redeclare class Plugin_Upgrader in /home/lighttso/public_html/wp-admin/includes/class-wp-upgrader.php on line 632
I'm using a premium theme. I had to wait until the theme's creators issued an update before I could update WP. I successfully updated the theme.
Is this a theme issue or a WP issue?
I'm using WP 3.4.2: can I only update to 3.5.1 from 3.5? Because I'm not getting any options for anything other than the latest version.
My site is functioning. I have not lost anything. Everything is viewable, it's just I can't update WP.
