Thank you for your help.
I understand. WPML is on my radar but I have some concerns about its potential effect on the database performance. Also, I like to use Poedit or Loco Translate to translate strings but the button texts don’t show up.
I’ll have to install WordPress several times for testing purposes! Please tell me how to replicate that aligned look. I couldn’t notice any change to the above mentioned code. I only noticed that you changed the Product Title Limit By to Lines and the Product Title Lines Limit to 1 but changing it back has no effect.
