That is good to know… It must have been some other issue that broke it but I couldn’t get it back working again so delighted to have found a plugin that will take care of it. I said I’d post it in case someone else would also prefer the plugin route!
I was using this but it had stopped working on my site after the recent Divi speed update. I tried Divi Machine from Divi Engine and it worked perfectly in the Builder – highly recommended and far less worry about bits breaking https://diviengine.com/product/divi-machine/
