Hallo Tobi, grĂ¼ss dich
Hey, Thanks for going Pro and welcome to the forums!
Sorry about the translations issues, let me try to help you fix those.
To be able to better support you I’d like to ask you to share your system information with me.
To get you started until then:
Normally translations are done in the .po files which you can find in the lang folder of the plugins, for example wp-content/plugins/the-events-calendar/lang/the-events-calendar-de_DE.po
You can edit these files either with PoEdit or with the Loco Translate plugin.
Cheers,
Andras
