The official resources addon. I know you are supposed to be able to replace the resource phrase and add your own. But I couldn't find a easy "search and replace" option in the phrases section? How can you do this?
Holy bleep, is that the only way? That is 264 (!) entries to translate... You'd really expect there to be a simpler way to edit resources text to something else, considering there are many that use that addon for other purposes (which is a good thing, it is quite versatile).You can use the new "Translate" feature in XF2.
It's still a fairly manual process, but it is easier because of how the list of phrases is laid out, and how they can be saved without a page reload.
Start by going to "Search phrases" under Appearance in the Admin CP.
Select XenForo Resource Manager as the add-on and search for phrases containing the text "resource". Then instead of clicking "Search" click "Translate" instead.
