I've asked a similar question a week back im surprised noone has run into this maybe it's just my installation if anyone has this problem please comment so I know its not just me.
On DNN 7.04 when trying to edit any page with the CONTROLBAR set not the RIBBONBAR
I hover on top of the black "Edit Page" button to reveal a dropdown menu with a blue "Edit this Page" button upon clicking on it instead of entering into "Edit Mode" I get redirected to my homepage.
This happens on any page of my site. The only way to enter edit mode is reverting to RIBBONBAR and selecting "edit mode" from the dropdown menu.
2ndly when inserting a module into a page and selecting a pane from the module insertion dropdown the module gets inserted into that pane with no problems. Now when trying to move a module already on a a page to a different pane that it is in, it will move and upon refreshing or changing to view or layout modes the module will jump back to the previous pane it was in.
If anyone is having similar problems please comment so i know its not just my installation.
