I am trying to set up the cron job, can't seem to get it to work. I keep getting invalid user/password. I am trying the HTTP method. I am using WordPress I am on a shared server.
Welcome to SE! Can you install cv? If so, I find that the most straightforward for cron. See https://docs.civicrm.org/sysadmin/en/latest/setup/jobs/#cv
For the HTTP method, does the user/password work when logging in via GUI? Does it work with curl or wget? (See same doc) Check that works before adding the complications of cron itself.
