I am using Polylang and loco Translation to translate my blog site. I'm adding the string translations manually and this works fine with the get_theme_mod part, but there is one place where I also want to add a custom string translation and after I add it manually it breaks the html and the css won't work.

Added custom string translation should look like this; no need for pll_e to work properly

But after I added pll_e to that section in index.html;

It breaks the html but the translation works. It looks like this; it looks like this

Does anyone know a solution? I think it has something to do with get_template_part and get_theme_mod since the same thing I did with the get_theme_mod part worked fine.

By the way, there is a difference between having pll_e and not having pll_e.

No pll_e with pll_e
