Signs, writtable book and renaming any item aren't working anymore.

Signs, writeable books, typing chat, and renaming any item aren't working anymore.{

What I mean for these as bugs. They're not working for some case of scenario. When typing in chat and signs are not showing to anyone else but yourself. When using writeable books are not working properly. Renaming items with anvil would never work. These Bugs Are really stressing me out. And I want them to be fixed again because I'm sick of tired of not be able to write, text, and renaming stuff. Please fix this soon so I don't stress out more.
