3.4 Database Update White Screen

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 using wp-admin/upgrade.php

-re-uploading all the files except the wp-content folder from a fresh download worked like a charm.

Thanks a ton.

Excellent! ??

FWIW, the odd back download does happen some time. Especially when thousands of other users are downloading the upgrade at the same time.

I encountered the same issue. Do I do each recommendation above step-by-step or just try one solution at-a-time?

Those solutions don’t overlap so you can try one at a time or do all three. Then run the upgrade manually using wp-admin/upgrade.php.

Edit: Also note, this thread was marked resolved; I looked at it by mistake. ?? Resolved threads indicates there’s no more problem for the OP.

Going forward please create your own.

I just removed the db.php file (database cache) from the plugins folder, and that solved the problem.

Just wanted to add that the exact same thing happened to me. I followed Jazoja’s advice (after manually uploading the 3.4 files except wp-content) and it worked. However, db.php is located in the wp-content folder, not the plugins folder.

– 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 using wp-admin/upgrade.php

Tried these, and I’m still having problems. I’ve never had this upgrade problem before. Actually 2 other sites updated just fine, and they’re on the same server! Any other thoughts?

I’m having the same issues as well despite a fresh manual install, all plugins disabled, and running the upgrade manually through the yourdomain.com/wp-admin/upgrade.php suggestions

How I fixed my site was by increasing the PHP memory limit. I added this to the top of my wp-config.php just after the beginning <?php:

define('WP_MEMORY_LIMIT', '64M');

If that doesn’t work, try increasing the limit to ‘128M’.

Just for another possible solution.

This has happened twice on my site (on a shared server with shared database servers), and somehow one or more database tables became corrupt. It was obvious when I set DEBUG to TRUE and tried to log in (lots of errors about a corrupt user table).

Running a MySQL repair on the database resolved it for me.
