Hi, two issues actually
1) We have installed different languages. When I download the package from the official website including languages for v.1.11 and then I replace the existing files in the folder "include/i18n", the language files always show "the originator of this extension can not be verified". See screenshot.
2) Is there a version of the language files for v1.11? It says the language files are for v1.10, even so they are the latest from your website.
