WordPress multisite: My Sites menu in the admin bar shows the same blog after updating to 3.5.1

Today I’ve noticed a little bug come out on my WordPress network running on a WordPress Multisite configuration.
In the admin bar the My Sites menu was showing the currently viewing blog a number of times.
Further looking revealed me that for every blog on the network that link was pointing to the current blog.

My first thought was ‘something went wrong in while updating WordPress to 3.5.1‘.
But I was wrong.

The cause of this bug was W3 Total Cache plugin.
To restore the functionality of the My Sites menu i simply network activated W3TC and then network deactived.

And the bug was gone!

    Thanks for that. Just had the exact same problem.
    I also figured w3 is doing some weird stuff. I had it deactivated but after the update I had to install memcache before I could get WordPress working again.

    • well thank you for sharing this addendum ๐Ÿ™‚
      I can’t verify this because I had memcache before the issue!

    Frustratingly that I had to search so long for such a simple answer. Thank you very much!
