#16630 closed defect (bug) (invalid)

Upgrade from 3.0.5 to 3.1 failed

For one of my blogs, an upgrade from 3.0.5 to 3.1 failed.

I debugged the issue to wp_cache_flush() hanging during the upgrade process.

To get the DB upgrade to go thru, this is the hack that I did:

File: /wp-admin/includes/upgrade.php

Method: wp_upgrade()

Comment out the call to wp_cache_flush() in line 364.

The DB upgrade went thru properly and I was able to login again.

I have been using W3 Total Cache on my blog. I'm not sure if that is what was conflicting during the upgrade.

Please try the support forums. Yes this was likely due to W3TC. I've sent a note to the author but it is likely a rare bug as the plugin does work in 3.1.
