Hi,
I have a model that I estimate well under Dynare 4.4.3 with intuitive posterior means and, most importantly, a definite posterior log data density. When I estimate exactly the same mod file, with the same data, with Dynare 4.5.0 to 4.6.4, I always obtain “Log data density is Inf” while the estimated parameters and other results are roughly similar.
I read the major uservisible changes from the Release of Dynare 4.5.0 email (2017), but I cannot understand what provokes such a difference.

Does the Dynare team aware of this issue? Can I rely on Dynare 4.4.3 ?

Is there a way to retrieve a definite calculation of the posterior log data density with the last Dynare version?

May I use the last Dynare version (which is assumed to be more robust than the previous ones, right?) and use the log data density (Laplace approx, before MCMCMH, which is definite) instead of the posterior log data density?
Thank you in advance for your help.
Thanks to all the Dynare team, you are doing a fantastic job!
Best,
Jonathan
