LiteSpeed Cache is Disabled Warning on WordPress

Posted on May 14th, 2019

 

As the name implies, the Litespeed cache is a cache and it is used in the Litespeed Web Server. The Litespeed web server is a substitute to the Apache Web Server. Some times we will face an issue that the lite speed cache is disabled as follows on  WordPress.

Litespeed cache

 

Here I’m telling about how to solve this situation. This error mostly occurs while a website is migrated from remote to the destination server. This can occur mostly the misconfiguration of the lite speed file.

This is a generic error that doesn’t indicate any cause of the issue.

Let’s have look how to solve this.

1) Login to the WordPress admin portal.

2) Navigate to  LiteSpeed Cache >> Report >> Report summary. Here you can see something like below.

Server Variables

SERVER_SOFTWARE = LiteSpeed

DOCUMENT_ROOT = /home/user/public_html

X-LSCACHE = on

LSWCP_TAG_PREFIX = 47b

WP_SITEURL = NULL

WP_HOME = NULL

WP_CONTENT_DIR = /home/user/public_html/wp-content

SHORTINIT = false

LSCWP_CONTENT_DIR = /home/user/public_html/wp-content

LSCWP_CONTENT_FOLDER = wp-content

LSCWP_DIR = /home/user/public_html/wp-content/plugins/litespeed-cache-bk/

LITESPEED_TIME_OFFSET = 21600

LITESPEED_SERVER_TYPE = LITESPEED_SERVER_ENT

LITESPEED_CLI = NULL

LITESPEED_ALLOWED = true

LITESPEED_ON = NULL

LITESPEED_ON_IN_SETTING = true

LSCACHE_ADV_CACHE = NULL

3) Check the values of the following variables:

LSCACHE_ADV_CACHE = true.

If LSCACHE_ADV_CACHE = NULL, then look into the wp-content/advanced-cache.php file where you can find a line define(‘LSCACHE_ADV_CACHE’, true);. If the line already exists, then it might be a permissions issue. Sometimes this won’t be the reason for the issue, and the plugin still doesn’t work. In this case, Login to WordPress dashboard Search for LiteSpeed Cache >> Settings >> Advanced and disable “Check Advanced Cache”.

LITESPEED_ON = true

If LSCACHE_ADV_CACHE = null, then this will be always NULL. Otherwise, if this value is NULL, then it means that you are not running with LiteSpeed Web Server. Check with the hosting provider.

LITESPEED_ON_IN_SETTING = true

If this value is NULL, then Login to WordPress Settings >> General page and set “Enable LiteSpeed Cache” to Enable.

4) If the above methods do not help you to resolve the situation, enable the lite speed then login to the server as the root user. Remove the advanced-cache.php file, and deactivating and reactivating the LiteSpeed Cache plugin. The file will be correctly regenerated and configured.

# rm -rf /home/user/publi_html/wp-content/advanced-cache.php
