Created attachment 1926 [details] Screenshot of toolbar Claws Mail 3.17.1 German translation has 100% according to https://www.claws-mail.org/i18n.php Still, the toolbar string/label "Wastebin"/trash is not translated
Hi, They're translated by default, but the toolbars are saved to preferences as they are customizable. "Wastebin" doesn't appear in the source code, so either you renamed Trash to Wastebin at some point, or we switched from Wastebin to Trash at some point. That makes Claws Mail unable to translate it when you switch language. You can either rename it to Trash or remove ~/.claws-mail/toolbar_main.xml while Claws isn't running (if you didn't personalize it), and Claws Mail should be able to translate everything.
Thanks for the explanation. The problem makes perfectly sense now. :-)
