Hi Frank
I have just found that my website still has errors with picture loading but I have tinkered with the tick boxes and now I think I have sorted it.
So for the benefit of other users, if you have ‘add to cart’, selecting variation or picture loading issues then these are my settings:
Optimize JavaScript Code? – ticked
Force JavaScript in <head>? – unticked
Also aggregate inline JS? – ticked
Exclude scripts from Autoptimize:- left as default
Add try-catch wrapping? – ticked
Hope that’s it now!
