Because ISPConfig 3.0.3 comes with some new features, it was necessary to update the Dutch Language file set. Till uploaded this language file set already to SVN, so it will be available with the next ISPConfig3 release, but if you want to have it already, here it is!
@Edge, Thanks for your feedback. I fixed it and replaced the file. I will contact Till to use the corrected version in SVN.
@Hans Thank you for your blood, sweat and tears to have this translated into Dutch. Good work! Nice regards Joost
