If LiteMage Cache has already been purged with no success, the cause is most likely due to an incorrect virtual host cache root setup for Multi-site.
Usually, the virtual host cache root should be located under /home/$USER/lscache and cannot be in a centralized location,such as RAM disk, for multi-site setups. Even in /home/$USER/lscache location, It can not be like /home/$USER/lscache/domain1.com/, /home/$USER/lscache/domain2.com and /home/$USER/lscache/domain3.com for multi-site. All multi-site domains should have only one cache root location, such as /home/$USER/lscache. “lscache” folder can be named differently, such as /home/$USER/turbocache.
If cache root is not located under /home/$USER/, it is likely that the other site cannot see these cached files. Please refer to our cPanel guide for cPanel environment cache root setup.
Once the correct cache root is set and the cache has been purged the problem should be resolved.
