I don't see an Update button. I see a "Save Changes". My steps are:
- select role in "Select Role to View / Edit";
- press "Load";
- deselect some capability;
- press "Save Changes" on the bottom
it save and reloads the page with the correct capabilities checked.
This saves the capabilities, and they work correctly. Now, if I, later:
- select same role as above in "Select Role to View / Edit";
- press "Load"
it loads the default capabilities and not the ones I have just saved via "Save Changes".
Hope this clarify. I have v1.4.8. Thanks!
