  • Should I activate the plugin on the mainblog?

    Yes 🙂

    The plugin should not be activated network wide.

    Hi Keith,

    Thanks for your reply.

    I have activated the plugin on the main site and have set it up successfully. Are you saying I shouldn’t activate the plugin on the subdomains? I don’t get how they will get a performance increase if I leave the plugin deactivated..



    If you are using the newest version of the plugin which I think you should, I don’t believe it allows network activation. For example…

    Do NOT activate here:

    [your domain]/wp-admin/network/plugins.php

    But DO activate the plugin here:

    [your domain]/wp-admin/plugins.php

    So I believe you are doing it correctly. If you want to use it on more than one site within your network just activate it separately for each site.

    Hope this helps and hope I didn’t confuse you 🙂

    Thanks Keith!

    It is a bit confusing though, cause I keep on reading that the plugin allows you to change things network wide, which this method does not seem to do..

    I also had to add code to my htaccess for all my subdomains..

    I’ve got a feeling I’m making a massive detour.

    I also get the cannot active minify rewrite URL error, everything else seems to work fine. Any thoughts?

    Anyone here looking at the latest release?

    @frederick Townes

    Yes, but it hadn’t been released yet during the previous discussion in this thread.

    Sure, just checking. The latest release supports network activation and network policy management.

    Ha! I didn’t notice the plugin got updated in the few days I was working with it. Thanks for the update!

    This however leaves me with a few questions:

    1. Should I delete the code I put into my .htaccess file, deactivate the plugin on the subsites and start over using the network wide setup?

    2. I recently activated cloudflare for all my domains and am wondering how to set this up if I change to a network wide setup of the plugin. Each subsite is mapped to a unique domain .nl and .tv. I have set these domains up as individual sites in cloudflare. Should I just activate cloudflare in the network wide setup? What would I put under domain section? Or should I activate the cloudflare section in the plugin on each subsite? Just want to set this up right.

    Thanks heaps for all the help guys!

    1. You should check the install tab to see what rules it’s recommending.
    2. No cloudflare needs to be per site.

    Thanks Frederick!

    I actually cleared my htaccess and your plugin was smart enough to add the new rules by itself. Great work!

    I was just wondering what the cloudfare login actually does. As far as I’m aware cloudfare does all its optimizing through the dns? I don’t want to change the w3tc setup again just for cloudfare unless it actually gives a speed optimization. So essentially my question is: what does logging into cloudfare add if you’ve already set up cloudflare through their website?

    Thanks heaps!
