@nicogdevweb, I’m sorry but I was not notified of this topic but did receive your comment on my website a couple of hours ago.

I have updated the plugin to support the latest version of CF7 and it should show up here shortly as version 0.9.6.

Thanks!

@mrinal, your solution worked for me, but with some strange effects.

I added those lines to config then logged in successfully. I then removed the lines, and was then permanently stuck in the admin panel. It would not let me log out, it would just go right back into the admin panel after clicking logout!

So I re-added the lines, then successfully logged out. I then removed the lines, and it automatically logged me back in. So I logged out again and everything appears to be normal.

WordPress team, you really need to look into this [Moderator note: There is no WordPress team]

@snthorv, maybe mod_security has blocked you? Try flushing your server’s firewall.

I’m also going to say that an IP whitelist for login attempts is needed. Larger organizations that have a lot of editors seem to trip the login limit fairly often. My only solution is to increase the number of login attempts per host, which is decreasing security as opposed to having an IP whitelisted.

Enable “Host custom files”

Then scroll down to the “Custom Files List”. Add the following to upload all blog.dir directories to the CDN:

{wp_content_dir}/uploads/*

Alright did another big update to this script to include links. Here is a write up: https://elementdesignllc.com/2013/06/w3-total-cache-cdn-to-local-fallback/

Ended up coming up with a javascript solution for myself:

$(window).load(function() {
    $('img').each(function() {
        if (!this.complete || typeof this.naturalWidth == "undefined" || this.naturalWidth == 0) {
            var source = this.src;
            this.src = source.replace(document.location.protocol + '://cdn.',document.location.protocol + '://');
        }
    });
});

This only works if your domain is non-www, and your cdn is formatted as “cdn.mydomain.com”. This looks through all images, checks if the CDN version loaded, if not, falls back to mydomain.com. Now I can turn down the Amazon S3 sync to once a day, and there are no noticeable performance issues.
