For the first alert, if you select the option on the pop-up to first clear out the error, does it return? If so I would recommend submitting a case in your customer group ( MyJive Secret Support Group Administration FAQ ) as a next step where a member of our support team can assist in additional investigations specific to your instance.
I would also suggest this for the secondary Jive Daily behavior you are seeing.
Yes it comes right back. Thank you for your help.
