But a little concerned. Can you please tell what this means? * Many Thanks. * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fcache-preload-error%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 10 replies - 1 through 10 (of 10 total) * [Marc Lacroix](https://wordpress.org/support/users/marcusig/) * (@marcusig) * [6 years, 1 month ago](https://wordpress.org/support/topic/cache-preload-error/#post-12706574) * Hi there, * We’ve had a few reports on that, and are looking into it. What you see is of no concern (it’s the error reporting system that’s not reporting properly). * Though it does mean that an error occurred when preloading. * Does it happen every time you preload? * Marc. * Thread Starter [narinder912](https://wordpress.org/support/users/narinder912/) * (@narinder912) * [6 years, 1 month ago](https://wordpress.org/support/topic/cache-preload-error/#post-12706614) * No, not every time. So far it has happened only twice while I must have preloaded cache about 50 times. * Narinder * [dgarcialopez](https://wordpress.org/support/users/dgarcialopez/) * (@dgarcialopez) * [6 years, 1 month ago](https://wordpress.org/support/topic/cache-preload-error/#post-12708941) * Same here!

It is an error that’s not handled properly. BUT it means that there’s an other underlying error on the server, which we aren’t able to reproduce. * Does anyone have [network errors](https://i.postimg.cc/R0nSwpSp/screenshot-ajax-errors.png) when getting these alerts? And errors in their PHP error logs? * Marc. * [tracian](https://wordpress.org/support/users/tracian/) * (@tracian) * [6 years ago](https://wordpress.org/support/topic/cache-preload-error/#post-12739933) * Same error: * function(){return f&&(c&&!b&&(h=f.length-1,g.push(c)),function b(c){n.each(c, function(c,d){n.isFunction(d)?a.unique&&j.has(d)||f.push(d):d&&d.length&&”string”! ==n.type(d)&&b(d)})}(arguments),c&&!b&&i()),this} * No network errors, though. I am running a Divi+WPML site, rather basic. * [JPC60](https://wordpress.org/support/users/jpc60/) * (@jpc60) * [6 years ago](https://wordpress.org/support/topic/cache-preload-error/#post-12755373) * Same here, same error on WordPress 5.4.1. * Hate to have to change plugins, will wait a little while longer for an update. * [Marc Lacroix](https://wordpress.org/support/users/marcusig/) * (@marcusig) * [6 years ago](https://wordpress.org/support/topic/cache-preload-error/#post-12755472) * [@tracian](https://wordpress.org/support/users/tracian/) [@jpc60](https://wordpress.org/support/users/jpc60/) Do you have any errors in the PHP error logs? * [JPC60](https://wordpress.org/support/users/jpc60/) * (@jpc60) * [6 years ago](https://wordpress.org/support/topic/cache-preload-error/#post-12755522) * Hi, * I have to admit I don’t know where the PHP error logs are located. I did just log on to my cPanel and see these general errors, but I don’t think this is what you meant? I am running a very old theme and PHP 7.3. * [Wed Apr 29 23:42:21.596942 2020] [access_compat:error] [pid 3374848:tid 47203256551168][ client 157.55.39.218:9715] AH01797: client denied by server configuration: /home/ john/public_html/raildig-build-projects [Wed Apr 29 23:42:19.893197 2020] [access_compat: error] [pid 3374865:tid 47203273361152] [client 157.55.39.28:3287] AH01797: client denied by server configuration: /home/john/public_html/robots.txt [Wed Apr 29 23:42:19.449674 2020] [access_compat:error] [pid 3374040:tid 47203229234944] [ client 157.55.39.28:3234] AH01797: client denied by server configuration: /home/ john/public_html/robots.txt [Wed Apr 29 22:45:54.686138 2020] [access_compat: error] [pid 2747187:tid 47203224901376] [client 207.46.13.210:2095] AH01797: client denied by server configuration: /home/john/public_html/raildig-build-projects[ Wed Apr 29 20:41:19.945641 2020] [access_compat:error] [pid 1498354:tid 47203271128832][ client 207.46.13.210:5342] AH01797: client denied by server configuration: /home/ john/public_html/blog [Wed Apr 29 20:41:13.720063 2020] [access_compat:error][ pid 1569715:tid 47203229103872] [client 157.55.39.13:8167] AH01797: client denied by server configuration: /home/john/public_html/robots.txt [Wed Apr 29 20:41: 12.568770 2020] [access_compat:error] [pid 1569715:tid 47203245913856] [client 157.55.39.13:7895] AH01797: client denied by server configuration: /home/john/ public_html/robots.txt [Wed Apr 29 20:09:02.192866 2020] [access_compat:error][ pid 1441605:tid 47203222800128] [client 207.46.13.210:3590] AH01797: client denied by server configuration: /home/john/public_html/blog [Wed Apr 29 19:38:26.297070 2020] [access_compat:error] [pid 819214:tid 47203241711360] [client 207.46.13.44: 4430] AH01797: client denied by server configuration: /home/john/public_html/ sitemap-pt-post-2016-02.xml [Wed Apr 29 18:57:36.486312 2020] [access_compat: error] [pid 823007:tid 47203222800128] [client 207.46.13.44:5674] AH01797: client denied by server configuration: /home/john/public_html/raildig-guest [Wed Apr 29 17:16:07.526077 2020] [access_compat:error] [pid 4154586:tid 47203273230080][ client 157.55.39.13:15172] AH01797: client denied by server configuration: /home/ john/public_html/robots.txt [Wed Apr 29 17:16:07.068619 2020] [access_compat: error] [pid 4155636:tid 47203233306368] [client 157.55.39.13:15064] AH01797: client denied by server configuration: /home/john/public_html/robots.txt [Wed Apr 29 16:30:49.409433 2020] [access_compat:error] [pid 3640414:tid 47203264825088][ client 157.55.39.218:2286] AH01797: client denied by server configuration: /home/ john/public_html/sitemap-pt-post-2011-01.xml [Wed Apr 29 16:30:45.394597 2020][ access_compat:error] [pid 3641890:tid 47203243812608] [client 157.55.39.218:1597] AH01797: client denied by server configuration: /home/john/public_html/ [Wed Apr 29 16:30:34.487650 2020] [access_compat:error] [pid 3641782:tid 47203266926336][ client 157.55.39.13:2722] AH01797: client denied by server configuration: /home/ john/public_html/robots.txt [Wed Apr 29 16:30:33.935662 2020] [access_compat: error] [pid 3640966:tid 47203271128832] [client 157.55.39.13:2568] AH01797: client denied by server configuration: /home/john/public_html/robots.txt [Wed Apr 29 14:29:58.681293 2020] [access_compat:error] [pid 2524521:tid 47203227002624] [ client 207.46.13.210:4117] AH01797: client denied by server configuration: /home/ john/public_html/2020 [Wed Apr 29 14:17:01.221937 2020] [access_compat:error][ pid 1922160:tid 47203243812608] [client 207.46.13.44:11013] AH01797: client denied by server configuration: /home/john/public_html/raildig-guest - This reply was modified 6 years ago by [JPC60](https://wordpress.org/support/users/jpc60/).
