Hi, all - long time member here (I believe I was the first ever customer for pMachine -> ExpressionEngine, back in 2001).
A site that I built a long time ago that runs EE 1.6.9 with MSM (yeah, I know I should upgrade) all of a sudden has all links going to the index page:
Note that any link you click on just returns to the index page. Nothing was changed when this happened.
What could be the reason for this? Will upgrading to EE 2.X help?
