I finally got the courage to chose the 'automatic upgrade' option to upgrade from 2.7.1 to 2.9.1
After waiting for an hour, I realized the automatic option would not be quick.
I let it run all night, and it seems the blog is back online, so I was hopeful everything was okay.
When I log into the admin panel, I get this error:
Fatal error: Call to undefined function set_screen_options() in /PATH-REMOVED/wp-admin/admin.php on line 49
The upgrade hasn't stopped - that screen is still blank and the Firefox spnning circle is still spinning.
I"m afraid if I kill it, I'll be in worse shape than I am now.
What do I need to do to:
a) ensure the install is finished
b) regain the ability to login to the admin panel?
I should have just left everything alone as 2.7.1 was working just fine. Sigh.
Thanks for any suggestions.
