The cron is not valid. perhaps you mean:
2-59/5 * * * *
Turned out to be a bug - you can enter the cron entry via searches-reports and it will work.
a212830 can you elaborate? I'm having the same issue. When you say you can enter the cron entry via searches-reports, what do you mean?
Yes, it's correct. Going to open a ticket on it...
Just ensure spacing is correct. 2(no space)-(no space)59(no space)/(no space)5(1 space)(1 space)(1 space)(1 space)
Sorry, yes, I do, but I still get the same error.
