Describe your issue

When I override form fields to replace TextField for WysiwygWidget I get TemplateDoesNotExist .

I have the feeling that is related to the loaders.py (I am using unfold together with the django admin and followed this insctrucctions: https://unfoldadmin.com/blog/migrating-django-admin-unfold/).

It seems that the templates loader is not looking at the right path (See image below: Templete Loader Postmortem). It actually doesn't even invoke the custom loader (i don't even know if it should, but I mention it anyways.)

Any help is greatly appreciated.

ERROR If I copy and paste the wysiwyghtml and related helper files in one of those paths I don't get the error but the widget does not show properly.

Ok, silly me. I forgot to put the "unfold.contrib.forms" in installed apps in settings.py.

"unfold.contrib.forms" added in settings.py
