Today I found this problem that I've never seen : "Cannot read property 'WCM' of undefined"
Inspecting the code I found this error on widget.js
Actually, I can't edit at all on my forms...no way!
Can someone help me?
Can you check if it's happening across all the browsers? Please clear the Browser cache and try creating a new form as well.
Can you remove or disable all the plugins you have in Chrome and try again.
Hi, I am not sure if I am the right person to assist you here for AEM Forms related query? I would suggest you can wait for other's reply and try in vanilla instance and if you see same issue, you can open a support ticket for Adobe to look into this.
