-===== Using Multiple Cache Plugins ======
+**Please Note**: This wiki is valid for v2.9.x and below of the LiteSpeed Cache Plugin for WordPress. If you are using v3.0 or above, please see [[https://docs.litespeedtech.com/lscache/lscwp/overview/|the new documentation]].
-To preface, it is **strongly recommended** to use only one full page cache plugin for full page caching. This guide is intended for admins who like some features from other cache plugins that aren't available in LSCWP.
+====== Using Multiple Optimization Plugins =======
-===== 1. Setup =====
+LiteSpeed Cache for WordPress has many optimization features in addition to our signature full-page cache, and as such, you probably don't need any other similar plugins. If you still want to use one of the other WordPress optimization plugins for whatever reason, that shouldn't be a problem, as long as you don't try to use the same features in both.
-First, set up the WordPress install with the //other// cache plugin to satisfaction. Doing this part first will make things easier because the full page cache will not be enabled yet.
-Once set up, disable the full page cache.
+For example, if you are using our full-page cache and our CDN support, then you will need to make sure that page cache and CDN support are disabled in whatever other plugin you use. Similarly, if you are using a minification function (for example) in another plugin, you will need to keep minification disabled in our plugin.
-===== 2. Installing LSCWP =====
+Duplicating functionality at best bogs down your server, and at worst breaks your site. So don't do it!
-[[litespeed_wiki:cache:lscwp:installation|Install and activate LSCWP]]. Upon activation, the following warning message will display if the above cache plugin uses the advanced-cache.php file.
+[[https://blog.litespeedtech.com/2017/08/02/wpw-using-multiple-cache-plugins/|To learn more about this, see our blog.]]

+===== Are these plugins compatible? =====
+Not all cache plugins are good candidates to pair with LiteSpeed. In order to avoid duplicating our functions, a plugin must either:
-If the message does not display, even after a few refreshes, [[https://wordpress.org/support/plugin/litespeed-cache|let us know]]. We need to know which plugin was previously used and which features are still used. It is possible that the cache plugin does not use the advanced-cache.php file, but it is just as likely that there is a hidden underlying issue.
+  - not include the same cache and optimization functions as LiteSpeed Cache at all, or
+  - include cache and optimization functions that can be disabled one-by-one.
-The message indicates that there is another cache plugin currently active, which is expected.
+===== Setting up the other plugin =====
+Before you install and activate LiteSpeed Cache, you should first get the other plugin working to your satisfaction. Doing this part first will make it easier because you can follow the plugin’s given directions without having to worry about how it will impact LiteSpeed’s setup.
-===== 3. Configuring LSCWP =====
+Once the plugin is installed, activated, and set up to your liking, //purge that plugin’s cache// to ensure there are no conflicts from the start, and then //disable the cache and all of the duplicate optimization functions that you plan to use in LSCWP//.
+===== Setting up LSCWP =====
-The last step is to configure LSCWP to leave the other plugin's advanced-cache.php file.
+[[litespeed_wiki:cache:lscwp:installation|Install and activate LSCWP]]. Upon activation, you should see the following warning message:
-Under Settings -> LiteSpeed Cache -> Advanced, uncheck the Check Advanced Cache option.
-{{ :litespeed_wiki:cache:lscwp:customizations:wpwzzc.png?700 |}}
+{{:litespeed_wiki:cache:lscwp:customizations:wpwzzb.png?800|}}
-After saving, the warning should no longer display. If the message is still there, [[https://wordpress.org/support/plugin/litespeed-cache|let us know]].
+This message indicates that there is another cache plugin activated and that it is using the WordPress ''advanced-cache.php'' file. This is normal behavior! If you see this warning, it means everything is working as expected.
+If you don’t see the above message, we need to figure out why. Try refreshing your screen a few times. If it’s still not there after that, it can mean one of two things:
+  * The other plugin you installed doesn’t use ''advanced-cache.php''
+  * There is an underlying issue that needs to be addressed
+In either of these cases, it’s best to [[https://wordpress.org/support/plugin/litespeed-cache|let us know]]. We’ll be able to tell you if this is normal for the other plugin you’re using, and if it’s not, we can troubleshoot the underlying issue.
+===== Configuring LSCWP =====
+Assuming you’ve seen the message above, the last step is to configure LSCWP not to use ''advanced-cache.php''. If the other plugin wants to use that file, we are going to let it do so. Navigate to **Settings → LiteSpeed Cache → Advanced**, and uncheck the ''Include advanced-cache.php'' option.
+{{:litespeed_wiki:cache:lscwp:customizations:lscwp-settings-advanced-annotated.png?direct&800|}}
+Save your changes, and the warning should no longer display. If the message is still there, [[https://wordpress.org/support/plugin/litespeed-cache|let us know]].
+Enable the cache and any optimization features you wish to use with LSCWP.
+===== Checking your work =====
+At this point, you should have both plugins working together in harmony, but you’ll want to do a quick test, just to be sure. To verify that your pages are actually being cached by LiteSpeed, you can [[litespeed_wiki:cache:lscwp:installation#testing|follow these steps]].
+If the page was not cached by LiteSpeed, then something in your setup is not quite right. [[https://wordpress.org/support/plugin/litespeed-cache|Contact us]], if you need help!
+If the page //was// cached by LiteSpeed, then the setup is finished. Don’t forget to take a look at your LiteSpeed Cache settings and see if anything needs adjustment. In general, the default settings are fine, but you might want to tweak a few things since you’ve got the other plugin running, too.
