Hi @knightycool and @yingscarlett I have deactivated all plugins and activated one by one, found that lazy loading of images,iframes,videos in sg optimizer and wprocket is the cause I think so.
Now disabled those options, so images and videos are showing up now.
But in homepage if you click on search or menu in header it’s not working and adds a # to url.
Also want to tell you that after lazy loading was disabled my blog loading speed gone up from 1.18 seconds to 3.18 seconds.
Recently updated to wordpress 5.7
So can anyone tell me how to overcome this. Thank You in advance.
