Re: Unable to render template … resolver could not resolve to a file in live server
What do you mean with submodules?
Notice that if you have an Admin\Controller\AdminController and an
Admin\Sub\Controller\AdminController, both of them will resolve their views
to admin/admin/index unless you use the controller_map configuration
Maybe your app is looking for the template in the wrong views directory and
it is not finding it.
To make sure this is your problem you can try to disable all the modules
but the one you want to test, to see if the error persists.
