OK, I've searched the latest 3.5.1 posting on upgrade problem, searched the forums for the error code I'm getting. Most resolutions for this problem seem to be a manual upload of WP3.5.1 files to the server (the idea being that some file has been corrupted and copying manually will resolve the problem)
No such luck, in my case. Here's the error code:
Fatal error: Call to undefined function dynamic_sidebar() in /home/victband/public_html/wp-admin/includes/widgets.php on line 80
The site involved is: http://www.victoriaband.ca/
The result in "no side bar on the site and no widgets"
I'm a medium level techie nerd in WP so I've tried all the following:
1. deactivated all plugins
2. changed to 2011 theme
3. over copied all system files
4. specifically over copied copied widgets.php
Any help is greatly appreciated.
