When I opened my site to edit this morning, I found a bunch of error markers on my DataSet name. After hours of searching to find an answer, I can assure you that my DataSet.id has not changed, and it is correct.
I managed to correct the problem this morning by logging out and back in again, but have found this same problem again. I can't clear it. I'm not sure if everything is working correctly. It does write to the DataSet when tested in preview, but the Developer Console shows no errors.
I have two (2) Macs, and it is the same on both. I have also cleaned both of the Macs extensively as I thought that it could have been some sort of cache issue.
Please see the photo included here. Any help is greatly appreciated.
