-===== Using Multiple Cache Plugins ====== +~~REDIRECT>​https://docs.litespeedtech.com/lscache/lscwp/admin/~~
- +
-Not all cache plugins are good candidates to pair with LiteSpeed. Our plugin is a full-page cache. That means LSCache stores copies of fully-assembled pages. **It’s strongly recommended that you only use one full-page cache.** In order for the other plugin to be a good fit with LSCache, it must either: +
- +
-  - not include a full-page cache at all, or +
-  - include a full-page cache that can be disabled. +
- +
-===== 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. +
- +
-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 its full-page cache functionality**. +
-===== Setting up LSCWP ===== +
- +
-[[litespeed_wiki:​cache:​lscwp:​installation|Install and activate LSCWP]]. Upon activation, , you should see the following warning message: +
- +
-{{ :​litespeed_wiki:​cache:​lscwp:​customizations:​wpwzzb.png?​700 |}} +
- +
-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 ''​Check advanced-cache.php''​ option. (The box will be green when “checked” and gray when “unchecked.”) +
- +
-{{ :​litespeed_wiki:​cache:​lscwp:​customizations:​wpwzzc.png?​700 |}} +
- +
-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]]. +
- +
-===== A Note about ExpiresDefault ===== +
- +
-A recent update to our plugin (version 1.1.4) added a warning that you might see: +
- +
-  ERROR 4010: In .htaccess file found one unexpected cache rule ExpiresDefault +
- +
-This will show up if your other plugin includes browser-caching functionality. We added the warning because browser cache can conflict with page cache and cause undesired behavior. +
- +
-To deal with this, edit your ''​.htaccess''​ file (in the root directory of your WordPress installation) and add the following line above the ''​ExpiresDefault''​ line: +
- +
-  ExpiresByType text/html "​access plus 0 seconds"​ +
- +
-(If an ''​ExpiresByType text/​html''​ rule already exists, either comment it out, or change it to match the 0-second rule above.) +
- +
-This rule will make it so that the pages that are cached by LSCWP are not included in the browser cache, but any other browser-cache behavior will remain unchanged. +
- +
-**Note:** As of v1.1.4, LSCWP will still put up a warning even after you’ve added this line. We’ll be changing that behavior with the next release, but until then, you can either ignore the warning, or insert a single space in front of ''​ExpiresDefault''​. If you add the space, the rule should still work as intended for the other plugin, but LSCWP will no longer detect it. +
- +
-If you have difficulty with this, drop by the support forum and [[https://​wordpress.org/​support/​plugin/​litespeed-cache|we’ll talk you through it]]. +
- +
-===== 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:​ +
- +
-  - Visit a page on your website while not logged in. +
-  - Reload the page. +
-  - View the page source (''​CTRL-U''​ or right-click,​ then “View Source”) +
-  - Scroll all the way to the bottom of the source code and check the last line. It should say something like: +
- +
-  <!-- Page generated by LiteSpeed Cache on 2017-07-31 15:56:52 --> +
- +
-If you don’t see the LiteSpeed Cache comment above, then the page was not cached by LiteSpeed and something in your setup is not quite right. [[https://​wordpress.org/​support/​plugin/​litespeed-cache|Contact us]], if you need help! +
- +
-If you do see the LiteSpeed Cache comment above, 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.+
