I can not send the mailing, in the report this message: "Delivery has not yet begun for this mailing. If the scheduled delivery date and time is past, ask the system administrator or technical support contact for your site to verify that the automated mailer task ('cron job') is running - and how frequently." what am I doing wrong? What should I correct? Thank you And if the problem is geolocation? And if the problem was the google API? I also had difficulty understanding OpenStreetMaps, maybe I was wrong with them? Is anyone practical with OpenStreetmap? Thanks In setting mapping I put this indicated in the screenshot:
If your cron is not running then there is nothing to 'tell' the Scheduled Jobs (which starts the mailing job) to run.
As a quick fix you should be able to go to your Scheduled Jobs (Admin > System > Scheduled Jobs, or /civicrm/admin/job?reset=1 in Drupal), find the Mailings scheduler job and use 'Execute Now' under the 'More' option - this should cause any overdue Mailings to be sent out.
To set up a cron so that the Jobs run automatically you need to follow the instructions here: https://docs.civicrm.org/sysadmin/en/latest/setup/jobs/
You also need to set any relevant Scheduled Jobs to be 'enabled' (under More)
