Problem with Dynare 4.5.7

Hello! I am facing bugs with the dynare 4.5.7 version constantly. I tried to run the code of Carriero et al. (2015) (Code downloaded from the website of Prof. Momtaz). It runs smoothly in the older version of 4.4.3 but not in 4.5.7 and 4.5.3. I constantly get the following notification, ‘Error using chol (Matrix must be square)’. I am facing this problem from the last couple of weeks. Is it a common problem?

Any suggestion regarding this will be highly appreciated.


This is not a bug, but a problem with mode-finding. What do the mode_check-plots indicate?
