I received a similar error message while trying to search in the forums for "correspondence"
http://en.lichess.org/forum/search?text=correspondence http://en.lichess.org/forum/search?text=something+went+wrong I'm using Chrome Version 32.0.1700.107 on a Macbook Air (OS X 10.9.1; Darwin 13.0.0)
----------- The error message ----------------
Something went wrong on this page.
If the problem persists, please report it in the forum.
Or send me an email at thibault.duplessis@gmail.com
Execution exception[[NoNodeAvailableException: No node available]]

Like hankm00dy I also noticed the 'sign in' at the top right corner of the error page instead of my username.
