I have four websites grouped sithin a central hub site. I haven't updated anything for a while, but on trying now I find that the edit changes that I make through the dashboard are not holding. They neither persist in the editing screen after I update, nor do they show up on the live page itself.
I also tried to deactivate one of the four sites but that has not had any effect. It does show on the dashboard sites list as deleted though.
I haven't updated my WP version because the last time I tried it screwed my system completely and I had to restore it whole. I would like to solve this problem without risking that again.
Thanks for your help,
