 * Do you know what causes this?
   And how I can fix it?

 * Hello,
 * Thank you for bringing this to our attention! 
   Our development team will address
   this PHP warning, which appeared in the latest version, in an upcoming update–
   possibly even the next one. In the meantime, you can [roll back](https://wordpress.org/plugins/wp-rollback/)
   to the previous version, TranslatePress Business 1.6.7, which should resolve 
   the issue. I will let you know as soon as the fix is available.
 * Thank you for your patience and understanding!
 * Kind regards,
 * Anca
