 ==== 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.

+===== 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 CDN cache solutions, such as CloudFlare, Sucuri etc.

-Another example when the user using sucuri and turn on cache on sucuri, you always see **"x-litespeed-cache: miss"**:
+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.

 It's LiteMage's job to cache dynamic content, therefore, if you are going to use CloudFlare/Sucuri 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.
