Well, the home page says the tutorials "should be compatible" with the 
listed versions, but there are several things that I note that won't 
work with 2018, including a few commands. I encourage you to provide 
feedback to the author(s) to note the problems with 2018, as surely you 
have had to change a few commands, e.g. to include -r (which is now 
mandatory for running grompp with restraints).

Again it seems there are inconsistencies in the input files. I only took 
a quick look through the tutorial, but I see no mention of making any of 
the index groups used in comm_grps in md.mdp.
