Error loading wordpress pages except home page in the host

I have a website with wordpress. It works on the local host, and I have uploaded and I have done everything for the DB in host. I have changed the ‘siteurl’ and ‘home’ in the DB. It works for the home page, but for other pages I receive the following error:

 Not Found

 The requested URL /تماس-با-ما/ was not found on this server.
