The problem occurs when the VoyeurX – XStore Child (folder xstore-child) is active.
when a different xstore child theme is active or the xstore parent theme (with the default out-of-the-box settings) it works just fine.
The child theme only contains the screenshot.png file and style.css with the necessary headers to define the child-theme. So any conflicts in the php code of the child theme can be ruled out.
– When the translation editor of translatepress is active all text is in English.
– The missing translations are part of the same short product description field.
