Hi, after I upgrade the last theme version, I can't change page things because when I go to save and update the page the site redirect on homepage and the changes doesn't save them. Why?
Sorry but the image does not work. Anyway, did you also tried to refresh permalinks under Settings > Permalinks section? If you did and it didn't helped, please deactivate all plugins and then check if saving works.
We can see that you have SUHOSIN extension installed. In many cases this addon is wrongly configured so please remove it from your server then and see if this would help.
It means that theme is not the problem then, right? Please just do what we wrote above and check because except above we do not have any other suggestion.
So if you don't have any control on the server where you are, we suggest to change hosting service as it's definitely not good to do not have control on such important part.

please check Appearance > System Status section for server limits because this could be the reason why you are not able to save.
