Great plugin, but it is not working for me so far.
I get this error when I try and save the po file:
Error: SyntaxError: JSON.parse: unterminated string at line 3 column 71 of the JSON data
And this one when I try to synchronize:
Error: SyntaxError: JSON.parse: unexpected end of data at line 3 column 6448 of the JSON data
I am running WP 3.9.1 on PHP5.3 / FastCGI with PHP Cache
File permissions for the language folder and its files are set at 777
