Look at your crontab file! It's probably full of junk, unless you asked “acme.sh” not to create the cron entries. The last crontab entry should be the one you want. “acme.sh” installed a crontab for the account under which you were doing this work. The certificates probably did not wind up in the right place, but adding options to the crontab line will allow you to place the certificates whereever you want them, so long as you have permissions to do so. Alternatively, if you look in the directory in which acme.sh was installed, there is a directory named for your domain. Within that directory is a configuration file which can be edited to suit your needs.
The point is that after you have accomplished the tasks outlined in this essay, you probably will still have some things which you will need to clean up.
