Today I updated to 7.7.2 and when I go to my frontend the images of the banners are not dound. I see that the route was incorrect. I try to modify it on my configuration of adrotate but was not possible for me.
I install another time 4.6 and also the banners images do not show.
For me the solution was like Maria Dolores said.
I go to my configuration and on the banners forler was banners only and I have to change it for wp-content/banners/
but now I can not upgrade to 7.7.2
