I have just migrated a site to a live server..
The site loads perfectly and all is well on the front end.
However, if I try to login to the admin, I get the silverstripe white/blue loading screen, the page stops loading (according to the browser) and the loading screen remains.
If I check the page source I can see that the html for the admin is there.
I can also add display: none; to #Loading and see the admin, but if I click any link the same occurs.
Looking at the hidden cms I can see that the right pane does not stretch to the right much, and pushes over the bottom grey bar a ways.
really not sure what to do. Works fine locally (other than every now and again I need to close FF and reopen to avoid the same 'type' of hang)
ps: I'm running the latest SS version. 2.4.2
