Thank you. I created the crontab on Siteground with a frequency of 1 minute as requested by the Mailpoet plugin of my wordpress site, but despite all the sending of the newsletters does not resume and the preview always refers me to my homepage. Siteground support has checked and says everything is set up correctly for them so I don’t know what to do. At this point I will have to remove Mailpoet and install another plugin. What I don’t understand is why for a year it has always worked and the problems arose only in January ….. could it depend on the theme?
