Yes I checked and its when memcache is active…but what could cause this? I use the same settings on more than 10 sites with no problem… and if memcache is not active the website is super slow to load… I tried with another theme on a staging site with the same content and its working fine with no problem…is there any settings in the theme we can enable or things to do regarding caching plugins (i can use another one) that would make the site runs fast enough without breaking it? I mean, its clearly related to the theme since its fine with all the tests I did and Siteground premium support think the same thing…deactivating memcache is not an option with the speed drop… feels like Xstore is super heavy to run…
