I use a set of modified mo/po files based on the translation you supplied – but with my own modifications included.
I noticed after updating to Woodmart 8.1 that a few of the translations does not work any more.
As an example the “add to compare” hover text is translated in my language files and works with Woodmart 8.0, but it isn’t translated in 8.1 with same translation files.
Does updating the theme include changes that require downloading new translation files?
