Hi,
755 would be the best permissions for htaccess. You can also try with 744.
Thanks,

Thank You so much for your reply.
In this page found on codex.wordpress.org I’ve read this:
.htaccess permissions
644 > 604 – The bit allowing the group owner of the .htaccess file read permission was removed. 644 is normally required and recommended for .htaccess files.
is it true?
644 is the default permission setting for the .htaccess file. Usually directories need 755 permissions and files, like .htaccess, need 644. You will likely find that it works just fine with 755 as well, but there is no need to hand it those unnecessary permissions. I like to go as low as possible, while still keep things working, for security reasons.
Is your htaccess in the root directory?
