WP 3 installed, DB updated, no plugins = blank wp-admin screen

    I think I’ve reviewed most of the “blank admin screen” threads.

    My site poinography.com loads as it did before the upgrade to WP3. However, my wp-admin page is blank (shows no source code).

    Renaming my plugins folder did not resolve the problem.
    Adding define('WP_MEMORY_LIMIT', '64M');to my wp-config.php did not resolve the problem.
    Renaming the themes folder does not resolve the problem, to the contrary, it made the blog itself go to a blank screen. I undid that rename…

    Any other ideas? I don’t ask for much, but I’d really like to be able to administer my blog! heh

    Access your server via FTP or SFTP, navigate to /wp-content/themes/ and rename everything except the /twentyten/ directory. This will force the Twenty Ten theme to activate and hopefully rule-out a theme-specific issue.

    Renaming all of the folders as you mentioned above won’t reset your themes. You’ll have to rename everything except Twenty Ten.

    FYI, one other thing that I tried that didn’t resolve the problem was using phpmyadmin to change the db_version to 15260.

    I will try your suggestion, but I noticed that in doing a ls -l of the themes directory everything has a group of “web” except for index.php and twentyten, which are assigned to group “nobody.” What makes that happen? How do I fix that? I reckon I don’t want to force it twentyten without resolving that issue first…

    Oh, and when I rename the other themes, what sort of name must I give them to ensure they are bypassed in favor of twentyen?

    This can sometimes happen when the themes are installed automatically via the Appearance/Add New interface, but it depends on the server’s configuration. You can safely change the ownership of the files to your FTP username with most FTP clients or contact your hosting provider and they’ll make the change for you.

    You can renamed them to anything. I prefer to add -broken to the end of the directory titles, ex: /default-broken/

    Okay, I got the ownership issue resolved by my webhost.

    When I rename the other themes to force it to the twentyten theme I still get the blank wp-admin screen. Worse, forcing it to the twentyten theme also makes the BLOG ITSELF go blank.

    As an experiment, I renamed twentyten to twentyten-broken and undid the -broken name change on classic (which was the theme I had been using). The blog loads again, but wp-admin is still blank.

    What do you suggest I do next?

    Try resettings your plugins via the phpMyAdmin method (it’s usually more reliable than just renaming the folder). If that resolves the issue, reactivate each one individually until you find the cause.

    Using phpMyAdmin to edit active_plugins to a:0:{} did not resolve the issue. Blog will load, but wp-admin still a blank screen.

    Now what?

    I do appreciate your patience!

    Try downloading WordPress again and delete then replace your copies of the /wp-admin/ and /wp-includes/ directories with fresh copies from the download.

    Sigh.

    That will have to wait until after work. Uploading it file-by-file takes a long time. I only hope that doing that doesn’t spawn another batch of “owner” issues that require my webhost to resolve…

    Whew. That takes forever! However…

    It seems to be working now. Thanks so much for your help.

    Well, “seems to be working” insofar as the wp-admin page isn’t blank…

    However, I can’t write a post (which is what motivated me to upgrade to WP3), I can’t make a new draft, nor can I edit a draft left over from before the upgrade. I’ll dive into that problem tomorrow…

    Now that you’re back in the admin panel, try decativating all plugins. If that resolves the issue, reactivate each one individually until you find the cause.

    I have no active plugins and I still can’t write drafts or posts, I can’t edit the existing (pre-upgrade) draft, nor can I leave/edit comments on published posts.

    I suspect that the(se) problem(s) is/are in the database. When I hover over the pre-upgrade draft, the footer of my browser says the link leads to post zero, even though my next post number should be much higher than that. If I click it, then I just get the page that shows a list of published posts, probably because the database can’t find a post zero.

    My web host is aplus.net.

    If you don’t mind, can you install a new blog in a new directory and database and let us know if the problem occurs in the new test blog?

    Sorry, but I do mind. If it works, then what would that prove? Explain how would setting up a test blog on the same web host help to narrow down the problem on the existing blog? If you can make a good case for it, then maybe I’ll go through that hassle.
