Thanks, Te Taipo, I think they were only concerned about incompatibilities, is there a way I can tell if a plugin such as Woocommerce has had custom changes?

Firstly James Huff and Gabor thank you so much!!! Your solutions worked perfectly.
All buttons in backend are working well and my Slider is loading great!

Gabor, as for your last suggestion I have copyed the text from conslole below, it doesnt seem to be related to any plugin?? Is this because James fix has resolved the issue? My understanding was his solution stops the plugins affecting each other when loading.

Thanks again, I am so happy with your help. These issues have been hanging over me for a while
