A while ago I created a new page in the top navigation and now I can't figure out how to go back into that page and edit it. My block editing is turned on and when I go into "manage blocks" the main menu block i there, but I can't figure out how to access it and edit my existing page?
If you can navigate to the actual page and you have permission to edit it, you will see a 'Edit Page Settings' in the administration block.
Alternatively, turn editing on and click on the cog next to the page name in the Main Menu block.
Thank you, yes, now I see that.
