Saving Cron doesn't have effect

-- HikaShop version -- : 3.0.0.
-- Joomla version -- : 3.6.5
-- PHP version -- : 7.0

Hi,

When I change the minimum delay between two cron tasks from 1440 minutes to 15 minutes and click on save the change won't be saved.
The minimum delay between two cron tasks stays on 1440 minutes.

I have this same issue on the test and acceptation server.

Hope you can fix it.

Kind regards,
Lumiga

Thanks! It's working fine now!
