Javascript conflict with Divi theme and some plugins

Hello,

Sounds like more a problem to me in the theme. They should check if an object is exist before using it, and they don’t. If they would, everything would work. Retina.js (is it the method you are using) is switching image, which might cause another script to not find the original image. Indeed, it’s changed.

WP Retina 2x uses many different methods, you can give a try to PictureFill, it is the recommended one ??

retina.js and picturefill both produce the error

IMG rewrite works fine, however

My first thought was the theme too, but the retina plugin appeared to conflict with another plugin too – HTML5 Responsive FAQ. this also now works now I’ve switched to IMG rewrite, but I haven’t yet been able to test on a retina device to see if the retina images are being served.

Apologies, it was only PictureFill that caused the error, retina.js works ok

Then it sound pretty bad.

Retina.js and Picturefill are two different methods, made by two different teams of developers. From tomorrow, Picturefill/Src-set will be adopted by WP 4.4 as a default way of displaying images in post. Your theme might not be ready for the jump…

If your theme doesn’t work with it, you can use the options in the Retina plugin to disable Reponsive Images with 4.4 and keep it to HTML Rewrite.

Maybe you should ask your theme dev why it is not working with Retina.js and PictureFill.
