    Try:
    – switching to the Twenty Eleven theme by renaming your current theme’s folder inside wp-content/themes and adding “-old” to the end of the folder name using FTP or whatever file management application your host provides.

    resetting the plugins folder by FTP or phpMyAdmin.

    – re-uploading all files & folders – except the wp-content folder – from a fresh download of WordPress.

    – running the upgrade manually via wp-admin/upgrade.php

    Wow. Thanks for the quick reply! I know just enough to be dangerous in the world of wordpress so please bare with me.

    I renamed my current theme to “nameoftheme-old” and now just a blank white page pops up. Is that what you meant by the first suggestion. If so, I take it I should move on down the list to the other suggestions???

    Thanks so much!

    Re-upload a fresh, unpacked, copy of the Twenty Eleven folder to wp-content/themes using FTP or whatever file management application your host provides.
    http://wordpress.org/extend/themes/twentyeleven

    Or, after reading your post again, do you mean I should do all four at the same time?

    Never mind…trying to the upload now. Thanks!

    I got the same upgrade.php?_wp_http_referer=%2Fwp-admin%2F redirect after upgrading from 3.4.1 to 3.4.2 on two sites where W3 Total Cache plugin was activated. After deactivating this plugin I logged into a 3.4.2 dashboard successfully and then activated W3 again.
    So, it’s better to disable W3 Total Cache before upgrading.

    I’m having the same problem. How did you manage to deactivate the plugin when you couldn’t access the dashboard @vjpo. Sorry to be so dense – please help.

    Figured that out – thank you 🙂

    Same thing just happened to me, so this is a quick fix: (if you upgraded without disabling total cache)

    1) Go in via FTP to your site
    2) In your plugins folder, locate w3-total-cache
    3) Rename it to something like w3-total-cache_bak
    4) Go to your wp-content folder and rename these following files
    – advanced-cache.php to advanced-cache.php_bak
    – db.php to db.php_bak
    – object-cache.php to object-cache.php_bak

    Now try and access your wp-admin dashboard.

    You should get in no probs.Go back to your FTP and rename your w3-total-cache_bak folder to it’s original name w3-total-cache

    You will be prompted with errors saying the files you renamed are not installed. Go back one at a time and rename them back and you’re golden.

    Whole process took 1 minute. Hope this helps you.

    Thank you so much for responding. I followed the steps you outlined and now get this message:
    W3 Total Cache Error: some files appear to be missing or out of place. Please re-install plugin or remove /home/content/42/8930942/html/wp-content/object-cache.php.

    I’m back to again to the original message 🙂

    ditto – on the phone with my hosting company for the past half hour and even they are struggling to figure out what happened. This is actually the first “upgrade” I’ve ever had trouble with in all my years with wordpress, but it’s also pretty frustrating.
    Has anyone figured out a solid solution yet?

    Try renaming the 3 files one more time, and the actual w3-total-cache directory. See if you can get back in. Then we’ll go from there. Let me know.

    I also see a file called w3-total-cache-config-preview.php – does that need to be renamed too?

    ever8302,

    Yes you need to delete or rename that file too. Also you might need to delete or back up your .htaccess then once your able to login again refresh your permalinks by going to settings -> permalinks and saving.

    I didnt delete the config-preview in my case and all worked, but as Chris mentions, not a bad idea.
