Hey Tereza,

You’re colleague’s code is not copied from the parent theme. The Text Domain in our parent theme has no backticks in the title line. Yours does.

Please have your developer change backticks to single quotes.

Please note that we do not provide support for custom codes including the ones we post here in the forum. If the issue persists, please kindly ask your colleague to fix the issue with the custom code.

It’s also recommended not to show warnings of a live site. You can disable warnings following the instruction in the debug article by WordPress here https://wordpress.org/support/article/debugging-in-wordpress/

Hope that helps and thank you for understanding.
