already asked. but waiting for answer week or more is not right support, but I have not other choices
like I write early, the last version of LSCache for Opencart 1.3.1 added support for Journal theme Separate Mobile View for tablet
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 this library for device detection is outdated.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.
