Steps not counting calories so annoying

So earlier today MFP was counting the steps and making the calories adjustment, as it was for the past week or so. But now I look and I am at zero for the past week as all the credits have been wiped out. I am using iphone, the settings have not been touched, and I've used this app for years without (me noticing at least) this happening. But I see it happens all the time by googling. I looked back to see if it was triggered by me adding strength training and I think that is what it is, because this happened AFTER I worked out today and added exercises. Again it was fine earlier. I have tried every which way to fix it, I click on the "iphone" label and then it says it is "disabled" but can't change it in settings or anywhere else. And I DID NOT disable anything either way. Any ideas?
