I would like to translate entries of display options section in YARPP plugin admin area with Polylang plugin. The default texts are "Related posts" and "No related posts". These strings do not appear in "string translations" section of polylang. I have tried
pll_register_string('name', 'string'); and
echo pll__('string'); but they did not work. I think I have to put something with
$ instead of
string. Any help appreciated.
