Title: admin-ajax.php Last modified: September 19, 2016 --- # admin-ajax.php * [Andrea](https://wordpress.org/support/users/aneises/) * (@aneises) * [9 years, 8 months ago](https://wordpress.org/support/topic/admin-ajax-php/) * Greetings * I´ve tested the plugin last weekend. Performance is slightly better than with my previous caching strategy (WP Rocket in combination with KeyCDN as a CDN for css,js and images). Loading time went down from 1.8 sec to 1.5 * My problem while testing was, that “admin-ajax.php” could not be leaded with 0 bytes. * Someone with an idea? * KR, Andreas Viewing 7 replies - 1 through 7 (of 7 total) * Thread Starter [Andrea](https://wordpress.org/support/users/aneises/) * (@aneises) * [9 years, 8 months ago](https://wordpress.org/support/topic/admin-ajax-php/#post-8196953) * And, yes, unfortunately, I need admin-ajax for some of my plugins. I´ve tried to find a way to exclude this file from KeyCDN without success. - This reply was modified 9 years, 8 months ago by [Andrea](https://wordpress.org/support/users/aneises/). * Thread Starter [Andrea](https://wordpress.org/support/users/aneises/) * (@aneises) * [9 years, 8 months ago](https://wordpress.org/support/topic/admin-ajax-php/#post-8208947) * Anyone with that problem? Any idea? * Thread Starter [Andrea](https://wordpress.org/support/users/aneises/) * (@aneises) * [9 years, 8 months ago](https://wordpress.org/support/topic/admin-ajax-php/#post-8221213) * Grrrrrrr, guess without any input I´ve to look for an alternative. Seemed so promising. * Plugin Contributor [ze3kr](https://wordpress.org/support/users/ze3kr/) * (@ze3kr) * [9 years, 8 months ago](https://wordpress.org/support/topic/admin-ajax-php/#post-8241080) * Sorry for the delay, but I don’t know which page have this problem (admin page or home page), and please tell me which plugin does not work and which theme you are using, so it’s easy for me to reappear this bug. * Thread Starter [Andrea](https://wordpress.org/support/users/aneises/) * (@aneises) * [9 years, 8 months ago](https://wordpress.org/support/topic/admin-ajax-php/#post-8241795) * Hi, thanks for your reply. * It’s a frontend problem. I’m using BeTheme, but the error seems caused by Hero Menu [http://heroplugins.com/product/hero-menu/](http://heroplugins.com/product/hero-menu/) what makes use of admin-ajax.php * The plugin (and also the theme) is sadly a premium / paid one, so I guess you won’t be able to install without purchasing it. * But I will setup a test page / clone of my site within the next days and send you the details, if you’re able to have a look. * Best regards, Andreas - This reply was modified 9 years, 8 months ago by [Andrea](https://wordpress.org/support/users/aneises/). * Plugin Contributor [ze3kr](https://wordpress.org/support/users/ze3kr/) * (@ze3kr) * [9 years, 7 months ago](https://wordpress.org/support/topic/admin-ajax-php/#post-8249623) * Could you please to / have you ever tried do these things and try to figure out the problem? * 1. Login to your site and go to the domain with wp-admin, see the page of the post/page and see if the problem solved. * 2. Disable this plugin(and nothing else), and go to the post/page without wp- admin domain, and append a query (like [http://www.example.com/?randomnumber](http://www.example.com/?randomnumber) to make sure no cache), see if it work. * This is only the ways to find where the errors are, not the ways to solve problem( it needs to do some change in code) * I think it might a bug of the rewriting system of this plugin. - This reply was modified 9 years, 7 months ago by [ze3kr](https://wordpress.org/support/users/ze3kr/). * Thread Starter [Andrea](https://wordpress.org/support/users/aneises/) * (@aneises) * [9 years, 7 months ago](https://wordpress.org/support/topic/admin-ajax-php/#post-8252435) * Hi * Shame on me. Period. * While testing I´ve notived, that for what reason whyever the zone ID wasn´set correctly. Guess while playing around with online/manual configuration and many tries, this slipped. I´ve corrected that, now everything works just like expected. * Thanks for your former reply, so I´d to double-check everything… * Great plugin, by the way. And thanks for your support 😉 * Regards, Andreas * P.S. Will try to implement on live URL tonight. - This reply was modified 9 years, 7 months ago by [Andrea](https://wordpress.org/support/users/aneises/). - This reply was modified 9 years, 7 months ago by [Andrea](https://wordpress.org/support/users/aneises/).
