1. Yes, the error seems to be due to different versions.
2. Your code does not do a proper error handling within the loop. You should not loop over all of Dynare. The proper way would be

Some questions on Loop over parameters

There are two issues here: phi is entering your steady state computations for the initial values. If you run a loop without updating initval, Dynare converges to a different steady state. Given the presence of multiple steady states, you should use an analytical steady state to select the correct/intended one. Your error handling is wrong. In Dynare 5, it should be stoch_simul(order=2, irf=0, ar=0, nofunctions, hp_filter=1600); para_rigid = 0.8:0.1:0.9; for i=1:length(para_rigid) set_pa…
