Perhaps I should mention, although it doesn’t seem relevant, that I got this report from the database upgrade by WP:
WordPress database error: [Duplicate entry ‘1’ for key 1]
INSERT INTO wp_terms (term_id, name, slug, term_group) VALUES (1, ‘Main’, ‘main’, 0)
WordPress database error: [Duplicate entry ‘1-category’ for key 2]
INSERT INTO wp_term_taxonomy (term_id, taxonomy, description, parent, count) VALUES ( 1, ‘category’, ”, 0, 51)
Update Complete
Your WordPress database has been successfully updated!
If you having problem with the theme is because the theme is compatible with the upgrade.
Thanks, that makes sense! But how do you change a theme other than on the Themes page?

On second thought, it doesn’t make complete sense. The site displays just fine with the ancient Default theme. It’s just the Themes page that won’t display.
I deleted the other oldie, Classic, but the problem persists.
If I delete Default, then the site doesn’t display.
Lane
Some more observations, but no solution in sight:
I deleted the old Default theme and renamed Twenty Ten’s filename to default.
Now the site shows up just fine in the Twenty Ten theme… but the wp-admin Themes page still comes up blank.
I assume something in themes.php is finding something in the database that’s causing it to exit, but I don’t know PHP well enough to debug it.

In wordpress 3.0 twenty ten theme is default and needs to stay that way do not delete or rename the theme switch to twenty ten theme and see id your admin works if it does not then there is problem in your update.
Well, I guess there’s a problem with the update, but I don’t know how to identify or fix it.
I now have three items in the themes folder: two folders (default, twentyten) and index.php.
The default folder is actually a copy of twentyten, and that’s the theme displaying my site.
And the Themes page still comes up blank.
