Make sure translators enter valid slug of the first post
|Reported by:||nbachiyski||Owned by:||nbachiyski|
Currently the slug of the first post is taken by the call:
_x('hello-world', 'Default post slug')
Then, this value is directly inserted in the database. If the translator entered a string in a non-sanitized form, the first post just won't open with pretty permalinks on.
If we call sanitize_title() in the string, we can make sure the right value goes in the database.
