Thanks for prompt reply Frank/AJ.
I found a solution to this. I ditched Masterslider (which uses jquery) and purchased CSS Slider (uses mostly CSS – enough for my needs). Only two js files inside my saved CSS Slider plugin are tinymce_plugin.js and ie.js – whether or not they used a lot not sure.
I’m able to enable the setting ‘Optimize JavaScript Code’ ONLY (in Autoptimize) leaving all others disabled (NB if I enable other settings eg. include in <head> or exclude jquery I receive huge dint in performance.
I also purchased ‘Indeed My Testimonials‘ which uses mostly CSS to render – there is no conflict with this – like before. There was conflict with my previous testimonials plugin and this is why I changed.
I am really happy with my website performance thanks to your plugin Frank.
Also, I purchased AJ @ WpFASTER.org course, thanks AJ!

thanks again to you both!
