See all our news

I have seen this time and time again, and I have translated the string in Codestyling Localization but this does nothing. It’s quite frustrating, because I am an individual, not a company, it ruins a lot of the Moesia FP plugins for me that they all talk about ‘our’

That string is translatable so it should work without issues in Codestyling.
But anyway, I just made a note to add an option to input this string directly from the widget options and it will be available in the next version.

If you can’t make it work in Codestyling and you want to do this until the next version is live, simply go to Appearance > Editor > fp-latest-news.php, hit CTRL+F, search for See all our news, find it and edit it. Save the file after that.
