This is a place to discuss how to adapt mojoPortal to the needs of different cultures. Before asking questions here please first review the localization documentation.
When adding an image to the Image Gallery (not the simple folder version) the error text "GalleryFileLabel not found in Resource.resx file" replaces the caption label "File" above the filename input field.
The GalleryFileLabel resource-item is present in GalleryResources.resx but not in Resource.resx.
Thanks for letting me know. I've fixed it here so it will be fixed in the next release.
