My Stack is Not Updated
Install WP Crontrol and check if
social_stacks_load_cache task is present in Tools/Crontrol.
If you see that its next run date is OK then please send support request so we can check your streams. Sometimes you can reach your server capacity and it can't handle current amount of streams. If it's scheduling is not OK like the date in the past please ask support from your hosting provider. Tell them WP Cron is not working correctly.
It's not here
If you don’t see tasks you need to create custom interval in Settings/Cron Schedules with next fields.
Then go back to Tools/Crontrol and create task
social_stacks_load_cache with these fields.
