Following the blog server migration on Tuesday, July 13, there will be a change to the URL for the Movable Type admin interface that will impact some users of the older MT version.
https://blogs.princeton.edu/mt
will now point to:
https://blogs.princeton.edu/mt4
The "mt4" URL will work exactly the same as before, but users of the current system will also have the "mt" option, and documentation will use the "mt" URL.
Most affected will be users of the older Movable Type 3 (Movable Type Enterprise 1.56) system. Since this instance will no longer use the "mt" address, these user will have to use the following address:
https://blogs.princeton.edu/mt3
There will also be an explanation of this on the "mt" login page after the migration.
