I have been at this almost a month now and still haven't been able to sort out the issue with LiteSpeed Cache. There's a setting in LiteSpeed for Object Cache, and it will not let me toggle it on!! Hostinger tech support insist that it's a theme problem. They asked me to activate another theme and the Object Cache toggle worked. Can you please give me some advice as to how I can get this to work? I tried setting up W3 Total Cache as an alternative but not user friendly. Before, someone from ClaPat said for Serano, they use Smush and W3 Total Cache. If this is the case, can you please send me the set up guides you used? Since I'm using Smush Pro, that would mean the image optimization in W3 should not be enabled. Do you have any good news for me? I like the Serano theme but I've had a headache regarding this issue. Attached are 2 screen shots. One furnished by Hostinger regarding critical error with theme. The second is form the Hostinger dashboard that shows Object Cache cannot be enabled. Please give me some good news. Thanks

Just to add...I've ditched LiteSpeed and am going with the plugins I get in Smush Pro. 

So can I assume that LiteSpeed cache is not compatible with Serano theme?
