Title: cache not detected Last modified: May 29, 2023 --- # cache not detected * Resolved [cositadmin](https://wordpress.org/support/users/cositadmin/) * (@cositadmin) * [3 years ago](https://wordpress.org/support/topic/cache-not-detected/) * We are having an issue where a page is not updating on desktop, but it does for mobile. While investigating I’ve run the cache test and got the following results. * > Page caching seems not working for both dynamic and static pages. > Error on dynamic page ([https://campground.myselkirk.ca](https://campground.myselkirk.ca)): > The plugin is not detected on your home page.

If you have disabled this plugin, please enable it back so that we can test your site and also if you have any other page caching plugin like WP Rocket or other installed, please disable that. * Thread Starter [cositadmin](https://wordpress.org/support/users/cositadmin/) * (@cositadmin) * [3 years ago](https://wordpress.org/support/topic/cache-not-detected/#post-16783759) * There are no other cache plugins installed currently, but I decided to check out htaccess file because we had been using WP Rocket previously. I saw there was still code from WP Rocket in the htaccess file, so I’ve removed it. I’m still not seeing the cache being detected but the error has changed now. * > Page caching seems not working for both dynamic and static pages. > Error on dynamic page ([https://campground.myselkirk.ca](https://campground.myselkirk.ca)): > The plugin is not detected on your home page.

Can you please try removing the htaccess rules except the WordPress default rule and the rules added by this plugin? Now sure why nothing is showing up in the response header. * Thread Starter [cositadmin](https://wordpress.org/support/users/cositadmin/) * (@cositadmin) * [3 years ago](https://wordpress.org/support/topic/cache-not-detected/#post-16786890) * This is what’s currently in the htaccess file * > ```wp-block-code > RewriteOptions inherit > > BEGIN WordPress > > RewriteEngine OnRewriteBase /RewriteRule ^index.php$ - [L]RewriteCond %{REQUEST_FILENAME} !-fRewriteCond %{REQUEST_FILENAME} !-dRewriteRule . /index.php [L] > > END WordPress > > order allow,deny allow from all > > deny from 20.106.252.78deny from 185.221.132.232deny from 20.109.51.143deny from 185.136.205.110deny from 20.38.4.239 > > deny from 20.83.59.236deny from 35.236.102.231deny from 38.111.114.211 > > php -- BEGIN cPanel-generated handler, do not edit > > Set the “ea-php81” package as the default “PHP” programming language. > > AddHandler application/x-httpd-ea-php81 .php .php8 .phtml > > php -- END cPanel-generated handler, do not edit > > deny from 20.169.228.36 > > BEGIN cPanel-generated php ini directives, do not edit > > Manual editing of this file may result in unexpected behavior. > > To make changes to this file, use the cPanel MultiPHP INI Editor (Home >> Software >> MultiPHP INI Editor) > > For more information, read our documentation (https://go.cpanel.net/EA4ModifyINI) > > php_flag display_errors On php_value max_execution_time 60 php_value max_input_time 90 php_value max_input_vars 3000 php_value memory_limit 256M php_value post_max_size 128M php_value session.gc_maxlifetime 1440 php_value session.save_path "/tmp" php_value upload_max_filesize 64M php_flag zlib.output_compression Offphp_flag display_errors On php_value max_execution_time 60 php_value max_input_time 90 php_value max_input_vars 3000 php_value memory_limit 256M php_value post_max_size 128M php_value session.gc_maxlifetime 1440 php_value session.save_path "/tmp" php_value upload_max_filesize 64M php_flag zlib.output_compression Off > > END cPanel-generated php ini directives, do not edit > > deny from 195.3.221.95deny from 195.3.221.96deny from 195.3.221.94deny from 195.3.221.1deny from 195.3.221.2/31deny from 195.3.221.4/30deny from 195.3.221.8/29deny from 195.3.221.16/28deny from 195.3.221.32/27deny from 195.3.221.64/27deny from 195.3.221.96/30deny from 195.3.221.100deny from 95.214.55.100/30deny from 95.214.55.104/29deny from 95.214.55.112/28deny from 95.214.55.128/26deny from 95.214.55.192/29deny from 95.214.55.200 > > BEGIN WP Cloudflare Super Page Cache > > The directives (lines) between BEGIN WP Cloudflare Super Page Cache and END WP Cloudflare Super Page Cache are > > dynamically generated, and should only be modified via WordPress filters. > > Any changes to the directives between these markers will be overwritten. > > ExpiresActive on ExpiresByType application/xml "access plus 0 seconds" ExpiresByType text/xsl "access plus 0 seconds"Header set Cache-Control "no-cache, no-store, must-revalidate, max-age=0"Header set Cache-Control "no-cache, no-store, must-revalidate, max-age=0"RewriteCond %{REQUEST_URI} ^(.)?/wp-content/wp-cloudflare-super-page-cache/www.myselkirk.ca/debug.log(.)$ RewriteRule ^(.*)$ - [F]Header set Cache-Control "no-cache, no-store, must-revalidate, max-age=0" > > END WP Cloudflare Super Page Cache > ``` > * The only things I can see are WordPress, Cpanel and the cache plugin. * Thread Starter [cositadmin](https://wordpress.org/support/users/cositadmin/) * (@cositadmin) * [3 years ago](https://wordpress.org/support/topic/cache-not-detected/#post-16789583) * Also as a part of cleanup I went through our database and WP-Config file and removed all entries from WP Rocket. While I have seen other pages that were not updating now are updating. Also I’ve gone and completely uninstalled the Super Page Cache plugin and reinstalled it, this page cache not showing is the only remaining problem. * Plugin Contributor [iSaumya](https://wordpress.org/support/users/isaumya/) * (@isaumya) * [3 years ago](https://wordpress.org/support/topic/cache-not-detected/#post-16793719) * Hi [@cositadmin](https://wordpress.org/support/users/cositadmin/), Thanks for implementing those fixes. Now I can see the plugin headers are being properly reported in the response header. Also looking at the response header, I can see that despite the plugin setting all headers properly your pages are still not being served from CDN cache. * This is because in the response header I see a `set-cookie` header for a cookie named `WP_SESSION_COOKIE`. This is the reason behind your problem. You see, if any plugin or theme that you are using in your WP site is setting any cookies at the PHP level, it creates those cookies using the `set-cookie` in the response header. * The problem is anytime Cloudflare sees `set-cookie` is present in the response header, it will never cache that page thinking that the cookie value might be used inside the page to show dynamic content. As a result the page should be served from the origin server. * You can try deactivating this plugin who is adding this cookie and you will see that your cache is working fine. You can also reach out to the plugin developers asking them if there is a way to use the plugin without using the cookies. * To make a site cache friendly, it is very important not to set any cookies at the PHP level. Instead do the checks at the JavaScript level and take advantage of the LocalStorage browser API. Moreover if cookies are must need to be set, it is best to set the cookies at the JavaScript level as it will not conflict with caching. * Screenshot: [https://i.imgur.com/GQmu9I4.jpeg](https://i.imgur.com/GQmu9I4.jpeg) Viewing 6 replies - 1 through 6 (of 6 total) The topic ‘cache not detected’ is closed to new replies. * ![](https://ps.w.org/wp-cloudflare-page-cache/assets/icon-256x256.gif?rev=3234997) * [Super Page Cache – Cloudflare Cache, Page Speed & Core Web Vitals](https://wordpress.org/plugins/wp-cloudflare-page-cache/) * [Frequently Asked Questions](https://wordpress.org/plugins/wp-cloudflare-page-cache/#faq) * [Support Threads](https://wordpress.org/support/plugin/wp-cloudflare-page-cache/) * [Active Topics](https://wordpress.org/support/plugin/wp-cloudflare-page-cache/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/wp-cloudflare-page-cache/unresolved/) * [Reviews](https://wordpress.org/support/plugin/wp-cloudflare-page-cache/reviews/) * 6 replies * 2 participants * Last reply from: [iSaumya](https://wordpress.org/support/users/isaumya/) * Last activity: [3 years ago](https://wordpress.org/support/topic/cache-not-detected/#post-16793719) * Status: resolved
