After upgrading the Woodmart theme from v5 to v6, my website became extremely slow. It takes around 10 seconds to load the first page. After the first page is loaded, the other pages are loading a bit faster. My website was much faster before the update.
Could you please disable all plugins that are not related to our theme and provide us your admin access so we can check it?
Also, allow us to switch between themes so we can see if it is related to our theme.
