On a DNN 5.5+: On the grid found at Admin > Languages, click on the edit pencil under the "System" column for the chosen row (language).
On a DNN < 5.5, browse to Admin > Languages, choose the target language from the "Available Locales:" drop-down found at the left of the screen, choose System, Host or Portal on the "Mode" radio-buttons
Notes:
- "System" will edit the base file for a given language. e.g. "GlobalResources.es-UY.resx"
- "Host" will create a custom version of the localized file for this installation. e.g. "GlobalResources.es-UY.Host.resx"
- "Portal" will create a custom version of the localized file just for the current portal. e.g. "GlobalResources.es-UY.Portal-0.resx" (in this sample, "0" is the current portal id).
Note: On a DNN < 5.5, this option is called "Site" instead of "Portal". - Browse the "Resources:" Tree found on the left side of the screen:
Local Resources > DesktopModules > My-Module-Name
Click on every "App_LocalResources" found on this sub-tree and edit the texts available on the right side of the screen.
Note: Remember to click on the "Save Resource File" link found at the bottom of the page, to confirm/save every file being edited/created.
