The problem went away after i messed up a bit with jetpack lazy load image settings but it could has been a problem related to the server, anyhow all ok now, thank you, you the best support !!!
I enabled too , it filled with a shitload of errors coming from a plugin named lightbox ,
i disabled it , but still the update behavior remained as before .
No it seems to work but after it tells that update-core has no right permissions , also giving it 777 it doesnt work,
all these problems when before it ever worked without to change any permission ,
why ?
