After installing the cron module in FUEL v1.2.1, I couldn't save a new cron script in the FUEL backend and received an error = "There was an error in creating your cronjob. Please check to make sure the file can be written to fuel/cron/crontab.txt" .
Even though the cron folder has been moved to fuel/modules/cronjobs/cron/, it seems the system still looks in fule/cron.
I managed to fix it be updating the cron folder path in "fuel/modules/cronjobs/config/cronjobs.php" to "modules/cronjobs/cron" and all seems to be working.
Am I on the correct path?
