Mainwhile i have activated lazyload of SG cache plugin after deactivating xstore theme’s lazyload https://prnt.sc/10ph19j. But in sidebar double images are appearing while siteground lazyload is activated https://prnt.sc/10pgk04 .
Please can you guide me to manege to use the lazyload of SG plugin as siteground’s lazyload had increased the loading performance of my website way better. Only because of the doubble images apperance in sidebar, i had to deactivate the lazyload of SG plugin.
