Getting some error on blog page and editor

Hello, guys,

I’m getting some errors on my blog page and blog editor. On the editor when I write my content, I suddenly get a popup on the top of the screen that asks to wait or leave the page but in both conditions, I lose my content then I need to retype all the things.

2nd Error:- Last edited time is not showing the current update time on my blog page, it is showing only past days’ update time. I update this blog today morning but is still showing only yesterday time.
