My forum has successfully installed and put into good use for about 1-2 months. Tuy nhiên it is not working today. I failed to translate the text does not appear, like this error:

Text translation Disappear After all - what is wrong?
Two possibilities:
- You did not fallow installation Instructions. You Must at Least Forum configure option language. Just configure mod
- You set the wrong Google API key - just set the appropriate value there.

[lang=vi]I checked it is normal option.
Option language: Vietnamese
API Key for windowsz.net: ABQIAAAAs2IPs1XLHdPymfri5WkD_xTf8GI3vNs3mVb8WN39cuNcTc-qzhRwT5Df7M1wFJSUzwlCiKHBDolgnw
