I saw a comment saying it's a cookie issue. Have you tried clearing yours since the move? That solved it for me and might help.

If you want to selectively delete data for Insanejournal (in Chrome) and not everything:
Settings -> privacy & security -> site settings -> cookies & site data -> see all site data & permissions -> search for IJ and delete
