I am fairly sure that Blackberry flowers on the 'old wood', not the
current
year's shoots. SO if you were pruning back the vigorous growth last year
that could explain why you have no flowers this year. Only prune stems
that
have borne fruit, and then take them right back to ground level.

That's correct, they definitely fruit on last years growth.
I used to train each new stem separately across the fence behind them as
they grew, and cut out last years' after fruiting.
Otherwise it's a tangle to get at the fruit next year.

Do they call it Spandeling or something like that? g
Dont know the wnswer to that but they definitely flower on last years
growth. Mine has a total of about 25ft. of growth from last year (I cut
back all of the previous years growth in the winter) anf I am seeing
many buds on side shoots from last years growth and am expecting about
10 lbs, as I had last year.

In the autumn/early winter cut out all the wood which has fruited having
tied in and trained the new wood as it grows.
