I am writing my PhD thesis with WinEdt and recently started to see the following error message. I didn't edit any settings nor change anything in the configurations. Can anybody help?

Runaway argument?
{\blx@citepunct@i {\blxcitecmd {footcite}}{{}}{345{masaryk.1965a}. Alle\ETC

    Welcome to TeX.sx! Please add a minimal working example (MWE) that illustrates your problem. Also note that if you indent lines by 4 spaces, they'll be marked as a code sample, as can be seen in Werner's edit. You can also highlight the code and click the "code" button (with "{}" on it). – doncherry Nov 16 '11 at 23:05
  • This probably means that you missed a } somewhere. Probably near a citation of masaryk.1965a. – Caramdir Nov 16 '11 at 23:15

    @Angie: Without an MWE that's impossible to tell. – Caramdir Nov 17 '11 at 0:01

    Second to @Caramdir's suggestion, I would sequentially comment out (or remove) lines of code until the problem is gone. Then edit them back in to hone in on the problem. Removing all the unnecessary stuff, if the problem still persists, post your MWE. – Werner Nov 17 '11 at 0:22

    It's usually best to make a copy of the file and edit the copy- leave the original alone just incase things get worse during the de-bugging process. – cmhughes Nov 17 '11 at 1:18
