Handle saving a context with a page template suggestion and no suggestion

Hi

I've created a new fork (3451442-handle-saving-a) but could not create the MR.

This issue happens when adding a new "Page template suggestions" or "Page title" and only if the form was not saved afterward.
I added the missing default configuration for the related plugins to fix the issue.

aimadbachar → changed the visibility of the branch 3451442-handle-saving-a to hidden.

aimadbachar → changed the visibility of the branch 3451442-handle-saving-a to active.

Hi

I have tested the MR !60
It works fine for me, there are no more errors
