Is there a way to translate the entry time property below the title in Greek Language as the meta property in the post title ?
That is date/time format of wordpress and it will apply for all language. You can change the style in Settings > General section.
oh, we did that, and it works in the blog tile info just fine as you can see here :
but it doesn't work when it's below the blog title in the header of the blog post
such as here :
Currently, the date format in single blog post is fixed the style. It will not apply the format in setting setting yet.
