Page Builder don′t save

Hi,

I have a trouble with page builder. Sometimes I do changes in the content of my web, but they aren’t saved. However, if I do changes about layout, those changes are shown correctly, but the changes in the content continue without shown them.

I have desactived all my plugins, only whit page builder. But the problem continue.

I have this problem since 6 months ago and I was waitting an update, but the new updates don’t solved this problem.

Help, please!
