- Visit <yoursite>/admin/tool/langimport/index.php
- Install multiple language packs.
- Under the 'Installed language packs' notice how you can only select one of these but the submit button reads 'Uninstall select language pack(s)'.
Solution -
1) Allow for multiple deletions of language packs.
2) Remove '(s)' from the string.
Personally I am in favour of 1.
