I have created a custom taxonomy called collection. Now, I want to add WYSIWYG editor to it. I came across this code on Github and it works fine on product category pages. I would want to implement the same code to my custom taxonomy term, collection. How do I go about this? I tried to replace product_cat with product_archive but the PHP editor could not save it and I received an error notice in return. tis is the error, Unable to communicate back with site to check for fatal errors, so the PHP change was reverted. You will need to upload your PHP file change by some other means, such as by using SFTP.
