Hi,
Sorry for that, try this steps.
1. Backup all the .po files you translate.
2. Install Codestyling localization.
3. Open the plugin page, and in french click Rescan, then view the translation strings, choose “swift-framework-admin” in the top for text domain.
4. Then change the “Select a shortcode” to french, click save .mo file.
5. Try view the page now.
If this too fails, I ask our developer to take a look at the issue.
Let us know,
Thanks,
laranz.
