NGINX Caching Proxy (ahead of Apache) 2. WP Super Cache, WP Rocket, etc on-site 3. htaccess/etc rules for Browser Caching **This way, you can ensure maximum efficiency!** The key is to purge when stale, so properly configuring your WP Plugin Cache is critical to ensuring that you don’t end up with cache misses due to stale data that could’ve/should’ve been purged by garbage collection, preloading, etc, rule-sets. ### Updating from v1 to v2.x.x **On every website running the plugin, check that:** 1. Website is reporting v2.x.x plugin version. 2. Plugin has been activated post-update. * 3. Config exists in the plugin settings. 4. API status checker reports OK. 5. /wp-content/tnc-toolbox-config/ folder is gone. _(* Change to main plugin file name may result in deactivation)_ ### Verifying cP+WHM Logs **If you’d like to ensure actions are firing properly at a deeper level:** 1. WHM > Tweak Settings > Logging > Enable cPanel API Log > On 2. WHM > Terminal > `tail -f /usr/local/cpanel/logs/api_log` 3. WordPress > Update a Post/Page, or explicitly Purge 4. WHM > Terminal > You should see the action fire! 5. WHM > Terminal > Ctrl+C to close the tail Note: To do this, you require `root` access to the Server. ## Screenshots * [[ * Top Menu Bar options for NGINX Caching. * [[ * Configuration in the WP Admin GUI. * [[ * Front-end per-page cache option. * [[ * Result of Selective Purging. ## Installation **Pre-reqs:** 1. To use ea-NGINX features, your Hosting needs to be on cPanel 2. Acquire a [cPanel API Token](https://docs.cpanel.net/cpanel/security/manage-api-tokens-in-cpanel/)( cPanel > Manage API Tokens) 3. Configure the TNC Toolbox plugin inside WordPress **How to install:** 1. Go to `Plugins` in WP-Admin 2. Click on the button `Add New` 3. Search for `TNC Toolbox` then click `Install Now` 4. Click on `Activate plugin` then `Settings` 5. Enter your API Token, User & Hostname 6. Save the config & use WP as-normal! **Selective Purging:** **Starting with v2.1.0, you can leverage Selective Cache Purging rather than the entire cache.** To do this, you need to complete some steps – else it will not work. You must be root. 1. Install the GetPageSpeed repository (dnf/yum) onto the Server: dnf -y install https://extras.getpagespeed.com/release-latest.rpm 2. Install ea-nginx-cache-purge module from GetPageSpeed repo: dnf -y install ea- nginx-cache-purge 3. Add `/etc/nginx/conf.d/server-includes/cache-purge.conf` File Contents: `proxy_cache_purge PURGE from 127.0.0.1;` 4. Rebuild & Reload: `nginx -t && systemctl reload nginx` **Updating from v1 to v2:** On every website running the plugin, check that: 1. Website is reporting v2.x.x plugin version. 2. Plugin has been activated post-update. * 3. Config exists in the plugin settings. 4. API status checker reports OK. 5. /wp-content/tnc-toolbox- config/ folder is gone. _(* Change to main plugin file name may result in deactivation)_ ## FAQ ### Does the plugin allow me to purge the NGINX User Cache? **Yes, it does!** All Users can do this easily via the button in the Admin top menu bar. ### Does it allow me to disable or enable NGINX User Caching? **Yes!** Admins can disable or enable the cache from the Admin top menu bar.

Many cPanel accounts primary run a wordpress site or more. Thanks for this developer stepping up and getting an in WordPress NGINX clear cache option enabled in WordPress dashboard. Would be great to get some intellegnet cache control to clear the cache for when pages/posts or products are updated. Not sure the nginx cache allows for the fine grain purging though. ![](https://secure.gravatar.com/avatar/e1bd22033fe1fa175f544f7b079b893ce56ca4dc6a5f2ec141af29ac9946d310? s=60&d=retro&r=g) ### 󠀁[NGINX Caching Solved](https://wordpress.org/support/topic/nginx-caching-solved/)󠁿 [danielpsyborg](https://profiles.wordpress.org/danielpsyborg/) April 2, 2023 This plugin saves me time logging into my server to clear NGINX Caching.
