Thanks so much for this great plugin!
Everything is working perfectly when editing pages with an admin-level account. However, if I try to set or modify a page's custom sidebar in any other account level (such as an editor), the selected sidebar does not "stick."
For example, if the drop-down for one of the sidebars is blank, I'll select the desired custom sidebar and then click "update" for the page. As the page is saved & the page's editing interface refreshes, the sidebar is once again blank.
Performing the same action while logged in as an "admin," everything works great.
Is there some way to fix this for non-admin-level users so that they can set custom sidebars?
