I'm the author of the Google+ Crossposting plugin. I can't figure out why localisation of the settings form of my plugin to German is not working.
I wrapped all strings in __() function, created the necessary pot, po, and mo files. I added
load_plugin_textdomain('g-crossposting', false, basename(dirname(__FILE__)).'/lang');
to my plugin so that it finds the language files.
Still, no success. The settings form is always in English.
I would really appreciate if anyone can take a look at the code and tell me what I'm missing. Thank you!
