Hello - upgraded to 3.3.1 and builder 4.1.3 and am faced with a tough issue. I get a session error when opening the themebuilder's based site.
Also, while in Site Administration, Mangage Builder Layouts, I also get the "session error" and cannot modify anything in the layout editor. Anyone have an ideas where to start looking? May be a confluence issue - but I haven't seen anything in either confluence or themebuilders release notes.
I have cleared cache, reinstalled the plugin, and tried in IE and Firefox. Same issue throughout.
