Advanced Permissións: Editors Can Add Layouts but Can't Add Blocks to those Layouts
PermalinkIs there a way to give them both permissions.. I really don't know what to do.
Thank you.

go to the page type defaults page for the page type you're using.
Dashboard > page types > your page type. Click "defaults"
Click on "add to main" then "set permissions". Make sure proper access is allowed for every section you want groups to add layouts and blocks!!
I have set permissions on the page I want editable to
View Area: administrators
Edit Contents: administrators
approve changes: administrators
In the "add to main" area I have set permissions to
View Area: administrators
Edit Area Contents: administrators
add block, stack and layout: administrators
Delete Area Contents: administrators.
I am now able to log in as testuser, which I have added to the Administrators Group, Navigate to the editable page and go ahead and add a layout and then a block, stack, etc inside any of the layout areas !!
See permissions attachments...
EDIT: Confirmed... same permissions settings on page type defaults. New page carries permissions and am able to log in as an "administrator" and create layout, with blocks inside.
You can have a look in the attachments, and I can't find the mistake.
Note: My Main Area is called Content ( Add to content) and my group to edit is called EDITORS
Thank you in advance...
