shooting failed while constraining a new density parameter #562
Error in Class: background_init(L:849) :condition (pba->shooting_failed == TRUE) is true; Shooting failed, try optimising input_get_guess(). Error message:

I added a new density parameter "rho_cc" in the class as other parameters exist there like "rho_fld", I followed the same procedure as other density parameters added like ''rho_lamda, fld, ..." and "Omega_Lambda,... Omega_fld" but while running montepython I am getting this issue in class, it would be a great help for me if anybody can help.
thanks in advance !!
