Hi, I have created a couple of components under the ‘Component’ heading in Cornerstone (Pro). One set works perfectly i.e. I can go in and edit the various elements (Buttons). However, a second set which holds all my Heading Components stopped working - it won’t let me go into the screen to edit them. I get the ‘iframe error’ screen attched. All other pages, headers and footer are working fine. (I’ve cleared the browser and theme caches - but this doesn’t fix it).
Can you tell how to fix this?
