Media Uploader translation problem
I have created wpdiscuz-media-uploader-pl_PL.po and wpdiscuz-media-uploader-pl_PL.mo translation files and placed them inside "languages" folder of the plugin, next to wpdiscuz-media-uploader.pot. The problem is that the translated phrases are not being translated and are still in english, for example:
msgid "Photo and Image Files"
msgstr "Zdjęcia i pliki obrazów"
What can be the reason?
