 ====== No “X-LiteSpeed-Cache: hit,litemage” Header ======
-In a Magento 1.x store, if the ''X-LiteSpeed-Cache: hit,litemage'' header is missing, it is an indication that LiteMage is not working properly. There can be various causes for this problem, but most likely a step was missed in the [[litespeed_wiki:cache:litemage:installation|LiteMage 1.x Installation Guide]].

 ===== Is LiteMage Enabled... =====
 ==== For Your License? ====
-For 1-CPU and lower licenses, you will need to purchase LiteMage as an add-on, while LiteMage starter is included in all 2-CPU and above license. If you just recently upgraded your license by adding LiteMage, you will need to register a new license key with the ''.../lsws/bin/lshttpd -r'' command and then restart LSWS.

 Did you try flushing LiteMage Cache and Magento Cache Storage? Do so, and then reload the page a few times.
-===== Is there an ESI Header? =====
+===== Have You Reached Your License's Cache Object Limit? =====
-If you see the header ''x-litespeed-cache-control: esi=on'', then the page is cachable but it has encountered a problem. You may have reached your license's cache object limit. Another possible cause is a conflict with another cache solutions, such as CloudFlare.

+===== Are You Using CDN Cache? =====
+CDN cache solutions, such as CloudFlare cache, Sucuri cache etc., may conflict with LiteMage. Please make sure to turn off CDN caches when using LiteMage.
+This example shows CloudFlare cache enabled:

-It's LiteMage's job to cache dynamic content, therefore, if you are going to use CloudFlare cache, it must be set up to only cache //static// content. See [[https://blog.litespeedtech.com/2017/11/20/magento-monday-litemage-cdns-and-tokens/|this blog post]] for more details.

+===== Are There Cache-Related Rewrite Rules in .htaccess? =====
+Please don't place ''RewriteRule (.*) - [E=Cache-Control:no-cache]'' in your ''.htaccess'' file. In fact, don't place //any// rewrite-rule-based cache directives into ''.htaccess'', unless there is a wiki or KB article instructing you to do so.
+Normally if you follow our wiki, LiteMage should work out of the box after installation, with no need to manually add anything. We have seen user-added rules break LiteMage and cause the cache miss header to display all the time.
