I have displayed all hidden files both in the unzipped directory of WP and in the FTP root directory. However, I still can't see the .htaccess file.
So I logged in my blog and went to Manage > Files. Then I clicked on the ".htaccess" shown on the right of the screen.
"Oops, no such file exists! Double check the name and try again, merci." was what I got on the screen. The same happened to the file "my-hacks.php (legacy hacks support)".
I think may be there is no .htaccess on the root directory. I have already read these pages: http://codex.wordpress.org/Changing_File_Permissions#Unhide_the_hidden_files
These do not seem to be helpful. What I'm asking is where I can find the .htaccess. If it doesn't exist how can I creat a .htaccess?
