I got this error for every mod file I want to run:

Reference to non-existent field ‘lb’.

Error in draw_prior_density (line 118)

f(find(x<bayestopt_.lb(indx)))=0;

Error in plot_priors (line 55)

[x,f,abscissa,dens,binf,bsup] = draw_prior_density(i,bayestopt_);

Error in dynare_estimation_init (line 323)

plot_priors(bayestopt_,M_,estim_params_,options_)

Error in dynare_estimation_1 (line 115)

[dataset_, dataset_info, xparam1, hh, M_, options_, oo_, estim_params_, bayestopt_,

bounds] = …

Error in dynare_estimation (line 105)

Error in OutputGap (line 481)

oo_recursive_=dynare_estimation(var_list_);

Error in dynare (line 235)

What should i do? I want IRFs and Prior-Posterior graphs.
