String translation

Hi there, I have translated  my site rockpix(dot)se with Polylang and have some problems with missed strings for Featured content and some other stuff on my frontpage because I am using child theme.I found out that you recommends WPML but I have already translated the whole site with Polylang before I saw that. I use, and missing strings to translate for:

• Header Media Title
• Site Header Text
• Header Media URL
• Header Media URL Text
• Excerpt options: Read more text
• Featured Content
• Promotion Headline
• Events

I found this for another theme of yours here in the support forum, but I need some help to adapt the codes for the Bold Photography Pro Child theme. Thanks in advance, ROCKPIX
