i think , you go to the ācron.phpā and comment line no 52 code sugar_die("cron.php is CLI only."); and then run directly /cron.php on other tab.
After run if job not trigger then go to your database and search sql āSELECT * FROM job_queue WHERE status!=ādoneāā then any result found force fully hard delete found results because cron job not check deleted=0 .
i hope its working for you.
