Unfortunately, the DotNetNuke developers did not succeed in providing issue-less resource files for several versions. This leads into additional effort during translation. To support translators, we provide corrected en-US language packs, that can be uploaded like any other DotNetNuke language pack.
DotNetNuke 4.4.0 and later support a more compact format for the language files. We converted all DotNetNuke languages files into this format, that loads faster and reduces memory consumption. We suggest to use these files for translation, because all translated files will get the new format as well.
