Serious issue with WordPress 3.6 update

Supposedly, if your site is built using a child-theme, updates to the parent do not affect changes to the child. Were any of the sites structured as child themes?

When you restored your broken sites with backups did that take you back to 3.5.2 (or whatever your earlier version was)?

No, we weren’t using child themes. The version we rolled back to was 3.5.2.

Did reverting to your backup successfully take you back to 3.5.2?

Yes, it did.

Did you deactivate all plugins prior to updating?

No, we didn’t.

See paragraph 4 in the first response:

It’s also possible that some plugins may not be compatible with 3.6 and may conflict(that is only my opinion).

Disabling the plugins before updating seems to be working for us.

Thanks for the assistance.

I am trying to update to 3.6. I deactivated all plugins and tried the update and still get this message:

Downloading update from https://www.ads-software.com/wordpress-3.6-new-bundled.zip…

I am not using any of the three plugins mentioned earlier in the thread. Anyone with any suggestions?
