In total and I made, language doesn’t change
Make sure the language code is correct in file name, and make sure you’ve uploaded both .MO and .PO files.
If all is correct please send those files to support[at]gvectors.com email address.

Please upload those using FileZilla and make sure the Transfer type is binary. Neither auto nor ASCII.
