Thanks for your speedy reply. I was running version 0.1.0, so just updated to 0.2.0 (though could have sworn I downloaded them from the same place...)
Have flushed all I can think of (db, dv, menus page, admin page), but am seeing a new problem now:
When I go to menus, I see Custom Menus in the left pane, but when I click on one of the menus it loads up a page in the right pane - seems to be corresponding the custom menu item with the equivalent page in the list. I know these are linked because when I make a change to one of these and then go to the content tab that change is still there.
Does it help if I make you a guest login? This is a test site so doesn't matter if stuff gets broken.
Brilliant, crossing fingers must have worked!
Just one more thing you should know; not a problem for me but suspect you will want to fix it:
When I delete menus from the left hand pane, it tells me that delete has failed and the menu still seems to be there, though when I refresh the admin page, the deleted menus are gone.
I have experienced some problems with deleting, it is on my list of things to fix/improve :). I have not seen a 'Delete Failed' message though. Maybe its because of a difference in Silverstripe version number. Cheers for the update though, I will push that to the top of my list of things to fix.
Glad that is is (for the most part) working for you now, hope you enjoy :).
