4. Make sure you disable all 'Full Page Cache' extensions – since these will interfere with LiteMage and may cause issues. Examples of these extensions include 'Extendware Full Page Cache'

Troubleshooting How to check if a page is served from LiteMage Cache or not
Use your browser's developer tool to check response header. If you see header "X-LiteSpeed-Cache: hit,litemage", that means the page is served by litemage cache. How do I clear or flush the LiteMage Cache?
Once LiteMage Cache has been enabled, a 'Flush LiteMage Cache' button will show up under System → Cache Management. If you click the buttons 'Flush Magento Cache' or 'Flush Cache Storage' it will automatically flush the LiteMage Cache. How to temporarily turn off LiteMage for certain URL from browser
Sometimes you may want to check if an issue is caused by LiteMage Cache being enabled but do not want to disable LiteMage Cache for everyone. You can add the following parameter "LITEMAGE_DEBUG=NOCACHE" to the end of the URL and the page will not be served from LiteMage Cache. For example if your URL to a page in your Magento store is http://mymagentostore.com.au/alice-in-wonderland.html you would change it to http://mymagentostore.com.au/alice-in-wonderland.html?LITEMAGE_DEBUG=NOCACHE to view the page not served by LiteMage cache. Can I enable LiteMage cache for just my IP address only for testing purposes?
Yes, and it is highly recommended to do so especially on production servers. To enable this, go to Magento Admin → System → Configuration → LITEMAGE CACHE → LiteMage Configuration → Developer Testing → Enable LiteMage Cache Only for Listed IPs
