    I have tried several times, uploading by ftp, removing and installing several times.
    It doesnt work and i am not sure what to do next.

    Of course i change the 777 chmod always.

    Thanks for your help.

    I see you've tried the standard ways. Problem is not getting the actual error, hard to pinpoint then.
    If you are conformable with editing a WordPress file. Add
    to wp-config.php. You can add it after
    * @package WordPress
    define('WP_DEBUG',true); //goes here

    Make sure there is no //, */ or /* before the define statement.

    Now when you activate you should get an error message.
    If you do it would be very helpfull if you post it here.

    Hi Frederick

    We solved this by email several months ago.

    I sent you an email with the problem.

    @darkpollo, what's your email address?

    Hi, my email is darkpollo at planetahuevo dot es
    And this is the one i sent you with the solution.
    This worked for me, not sure if this will work for others.

    "Hi Frederick,
    i managed to install it.
    The problem were two, first, if you install it without uploading, just
    from the WP admin site, it does not work (not sure why).
    Also, my wp-config was 444 for seurity reasons, so it needs to be 644
    to activate the plugin."

    So, first, upload it manually using FTP.
    Look the wp-config permissions to make sure it is writable before to install.

    Just tried installing...unsuccessful:

    Plugin could not be activated because it triggered a fatal error.

    Did this define('WP_DEBUG',true);

    Activated again.

    Got a number of warning notices but the plugin installed.

    So I am moving forward. Can I assume your plugin will work now?

    Got this error:

    It appears Page Cache URL rewriting is not working. If using apache, verify that the server configuration allows .htaccess

    But I know that other things I put into my .htaccess work on my apache server.

    So I don;t know what to do with this error.

    In all honesty, the site runs poorer than it did before the install. Backing it out.

    I'm also running into this same fatal error:

    Parse error: syntax error, unexpected T_OBJECT_OPERATOR in [my website's URL]/wp-content/plugins/w3-total-cache/lib/W3/PluginProxy.php on line 56

    I'd love to be able to cache my site...any ideas on how to remedy this?
