Header/Footer Disappear After Enabling LiteMage Cache

Problem: After re-enabling LiteMage Cache, the sites header, footer, and other dynamically loaded blocks (or the LiteMage specific options under System > Cache Management in the Magento Admin Panel) disappear.

Cause: Litespeed_Litemage output was mistakenly disabled

Solution: Log into Magento Admin Panel, go to System > Configuration > ADVANCED > Advanced > Disable Module Output, make sure Litespeed_Litemage output is enabled, then save config.

Notes: The correct way to disable LiteMage module(not only output) is: System > Configuration > LITEMAGE CACHE > LiteMage Configuration, set “Enable LiteMage Cache” to “No”.
