Schedule Tasks are not running automatically. When we run from the admin portal we see no issues. I have validated the Store URL and they look good. How to restart or enable these tasks that suddenly stopped running. I see this error in the error logs A public action method 'runtask' was not found on controller 'Nop.Admin.Controllers.ScheduleTaskController'.
What version of nopCommrce ? All enabled Schedule Tasks should run automatically Did you try stop / start the webserver or reboot the server ? Then check the error log again
