    Hi Transversalys,

    I have found the same problem - no ideal fix but I can at least get your admin back up (assuming you have enough access to your server?):

    Step 1 create a folder to move somes file to

    move the /plugins/w3-total-cache folder and all contents into the folder

    move the following four files from the /wp-config/ folder:


    into the storage folder and you should be back up and running (without w3tc however)

    I look forward to a more comprehensive fix from the development team.

    Same error. It didn't crash my admin, but I can't activate the plugin (any attempt to do so results in fatal error). Please advise on a fix.

    Thank you.

    I have just discovered my RSS feeds ceased to be updated approx. the same time as I completed this update. Can anyone confirm if this might be due to the update or unrelated! Thanks.
