Suddenly stoped working! sharepoin 2010 workflow

Apr 23, 2013 at 1:06 AM
i have used this in several workflows and suddenly it stopped functioning.

i use the invoke c# for the Replace() function and have it return to a variable - what ended up getting written to the variable was: "Unknown function: [Replace() ]." after working perfectly for weeks.

i'm going to try and redeploy and see if that helps.

anyone else run in to this?
