Title: WPFC & Cloudflare issue Last modified: October 2, 2025 --- # WPFC & Cloudflare issue * [Kresimir Pendic](https://wordpress.org/support/users/gorostas/) * (@gorostas) * [8 months, 1 week ago](https://wordpress.org/support/topic/wpfc-cloudflare-issue/) * Hi guys, I’ve been very happy user of WPFC for years now.. and CloudFlare also.. but I do suspect either some CF change or plugin update change does issues on my pages. * I’ve been having for years 2 cache fallback system successfully setup (having locally generated / served html pages via WPFC for non logged in users + CF did serve it fast) – while logged-in users did have cache bypass (CF did listened my nginx headers and passed dynamic content to users) – but recently does not work (I have to either disable WPFC itself or enable it and loggedin users gets cached pages) On my server I’ve been using standard nginx directive: * ```wp-block-code if ($http_cookie ~* (comment_author|comment_author_|wordpress_logged_in|wp_woocommerce_session)) { set $no_cache 1;}location / { if ($no_cache) { try_files $uri $uri/ /index.php?$args; } set $serve $fullurl${uri}index.html; try_files $serve $uri $uri/ /index.php?$args;} ``` * I’ve had played with disabling api token CDN connection, and ON|OFF enable cache of WPFC – but nothing worked – except when I disable plugin it self.. * I do realise that this could be complicated setup and you can direct me to support if its needed – kindly Kres. * note: site is in preload list => hsts ([https://hstspreload.org/?domain=udahni.com](https://hstspreload.org/?domain=udahni.com)) - This topic was modified 8 months, 1 week ago by [Kresimir Pendic](https://wordpress.org/support/users/gorostas/). * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fwpfc-cloudflare-issue%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 10 replies - 1 through 10 (of 10 total) * Plugin Author [Emre Vona](https://wordpress.org/support/users/emrevona/) * (@emrevona) * [8 months, 1 week ago](https://wordpress.org/support/topic/wpfc-cloudflare-issue/#post-18664878) * did you add the cloudflare integration?

I’ve tried to change it to respect my nginx header – tht did not help either * ![](https://i0.wp.com/i.imgur.com/veudCub.png?ssl=1) * Now I’ve enabled CF bypass all caches and now I get cached pages for loggedin users and guests.. * ![](https://i0.wp.com/i.imgur.com/JdpYswy.png?ssl=1) - This reply was modified 8 months, 1 week ago by [Kresimir Pendic](https://wordpress.org/support/users/gorostas/). * Plugin Author [Emre Vona](https://wordpress.org/support/users/emrevona/) * (@emrevona) * [8 months, 1 week ago](https://wordpress.org/support/topic/wpfc-cloudflare-issue/#post-18664952) * WP Fastest Cache checks that the visitor is logged-in or not. I do not think that WP Fastest Cache causes the issue. * are you using a server-side cache system such as proxy cache as well? * By the way, Can you enable the “Development Mode” on the cloudflare panel and try it again please? * Thread Starter [Kresimir Pendic](https://wordpress.org/support/users/gorostas/) * (@gorostas) * [8 months, 1 week ago](https://wordpress.org/support/topic/wpfc-cloudflare-issue/#post-18664998) * Hi, now I’ve switched Development mode on CF for my domain – and also enabled WPFC – this are my settings: * ![](https://i0.wp.com/i.imgur.com/1jNZgeO.png?ssl=1) * I do not have persistent cache – but low level (php) opcode cache only * ![](https://i0.wp.com/i.imgur.com/RJg6to6.png?ssl=1) * Plugin Author [Emre Vona](https://wordpress.org/support/users/emrevona/) * (@emrevona) * [8 months, 1 week ago](https://wordpress.org/support/topic/wpfc-cloudflare-issue/#post-18665016) * you should not use the opcache. * Thread Starter [Kresimir Pendic](https://wordpress.org/support/users/gorostas/) * (@gorostas) * [8 months, 1 week ago](https://wordpress.org/support/topic/wpfc-cloudflare-issue/#post-18665076) * Dear Emre, thanks for input – I’ve added into my ini * `opcache.enable=0` * and it is not active.. (but installed) – and now I get good results with normal WP logged in users, but now sociale ones (like Google login) .. I’ll have to invest more time it – kind regards! * Thread Starter [Kresimir Pendic](https://wordpress.org/support/users/gorostas/) * (@gorostas) * [8 months, 1 week ago](https://wordpress.org/support/topic/wpfc-cloudflare-issue/#post-18666462) * Quick question [@emrevona](https://wordpress.org/support/users/emrevona/) . ,, I did found issue else where – because I have custom sec settings defined in my wp-config like this * ```wp-block-code define( 'COOKIEHASH',md5( 'https://domain.xzy' ) );define( 'LOGGED_IN_COOKIE', '1234_' . COOKIEHASH ); ``` * then plugin cant recognize my cookies – its hardcoded `wordpress_logged_in` string in `excludeAdminCookie` method.. * ![](https://i0.wp.com/i.imgur.com/uzUkzcP.png?ssl=1) * I’ve been thinking.. what do you say for example to add new constant for example like this * ```wp-block-code define('WPFC_CUSTOM_LOGGED_IN_COOKIE', '1234_'); ``` * and then use it in rule? If not I think I could get that on nginx side – but that looks like alternative to me * Thanks, Kres * Plugin Author [Emre Vona](https://wordpress.org/support/users/emrevona/) * (@emrevona) * [8 months, 1 week ago](https://wordpress.org/support/topic/wpfc-cloudflare-issue/#post-18666492) * sorry but I cannot add it. * Thread Starter [Kresimir Pendic](https://wordpress.org/support/users/gorostas/) * (@gorostas) * [8 months, 1 week ago](https://wordpress.org/support/topic/wpfc-cloudflare-issue/#post-18666652) * No problem, one that in need like me can easily hook into init and do extend your plugin class and override that method if in need, thanks * Plugin Author [Emre Vona](https://wordpress.org/support/users/emrevona/) * (@emrevona) * [8 months, 1 week ago](https://wordpress.org/support/topic/wpfc-cloudflare-issue/#post-18667239) * you are welcome Viewing 10 replies - 1 through 10 (of 10 total) The topic ‘WPFC & Cloudflare issue’ is closed to new replies. * ![](https://ps.w.org/wp-fastest-cache/assets/icon-256x256.png?rev=2064586) * [WP Fastest Cache - WordPress Cache Plugin](https://wordpress.org/plugins/wp-fastest-cache/) * [Frequently Asked Questions](https://wordpress.org/plugins/wp-fastest-cache/#faq) * [Support Threads](https://wordpress.org/support/plugin/wp-fastest-cache/) * [Active Topics](https://wordpress.org/support/plugin/wp-fastest-cache/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/wp-fastest-cache/unresolved/) * [Reviews](https://wordpress.org/support/plugin/wp-fastest-cache/reviews/) ## Tags * [cache](https://wordpress.org/support/topic-tag/cache/) * 10 replies * 2 participants * Last reply from: [Emre Vona](https://wordpress.org/support/users/emrevona/) * Last activity: [8 months, 1 week ago](https://wordpress.org/support/topic/wpfc-cloudflare-issue/#post-18667239) * Status: not resolved
