Wednesday I went for a bike fitting and they made a few adjustments to my Road bike to get my angles correct
Today I did the same ride, back was killing me again from 40 to 60 kilometers, but today my knees were fine........ we also did the ride slower today by 1kph
What’s with the lower back pain on hills?.

I'm a trendy consumer. Just look at my stupid phone.
Bike fit is not an exact science, despite what they tell you and is geared toward racing in the science part, some bike fitters are a bit more sympathetic and age aware. It might be worth returning to the bike fitter and seeing if they can tweak your fit, most of the ones I know would be only too happy to help and wouldn’t charge to sort out the issue.
One possibility is that the fit is good, and your now able to push harder so the muscles are just doing something they’re not used to. You could try stretching exercise, and see if hat helps.
Bike fits - no science at all really. In practice the human body is a variable item within the main design envelope and wants various positions on a bike to be comfortable, efficient, fast, more stable and/or a list of other attributes required by different styles or habits of bike riding. Moreover, bike fits, as you suggest, are often about some theoretically most-aero or best power-producing position rather than anything else.
Personally I now find I need to be more upright than when a racing fellow, to avoid a general ache of the upper back and neck. Others I know of my age need to have a low front end as it's their lower back that's vulnerable to too much weight acting through it. so a low front handlebar takes some weight off their spine albeit at the cost of stressing their hands, shoulders and neck a bit more. The history of our bodies, as well as their genetic makeup, often requires we adapt in different ways to do different things as we age. Past injuries can be demanding!
Stretching never worked for me although others say it helps. I spent a 6 month trying to make pre-exercise stretching a habit and only achieved half-a-dozen strains from trying to stretch too much too soon.
