I have a cronjob and over and over using your service (never before) we get status off after a while.
If we purchase a year credit, will then easycron automatically be on status on so that I do not need to login every hour?
For free plan, a cron job will be disabled by EasyCron if it encountered 2 consecutive failures (cron timeout or other issues). Upgrading your plan will lift cron timeout limit and the error tolerance (More details is at Plan Page). Generally, if you cron script doesn't take long to execute, upgrading will prevent your cron jobs from being disabled.
