I really appreciate your kind and quick answer, but I’m not so skilled at coding…,
I had been looking for “_x” in the editor, too. But there is no “_x” before “all rights reserved” (in footer.php)
There is “_e” before “last modified” (content-single.php)
I cannot find “Published on”. Could you give me a hint?
I only found _x twice in the Archive.php.
