already asked. but waiting for answer week or more is not right support, but I have not other choices
Mobile detection in LiteSpeed cache plugin for Opencart isn't synchronised with mobile_detection library. This library can differentiate between cell phones and tablets, but LiteSpeed vary cache control can't, because there is only 1 cache control define for cell phones AND tablets. That's why it doesn't work correctly.
Btw. this library for device detection is outdated. Last update was released 2 years ago and is fault tolerant. In my mind mobile detection in LiteSpeed cache plugin for OpenCart should be complete new developed.
