Hello,
Thank you for letting me know of this issue, it seems that currently Google restricted the Free Google Translator service the plugin was using, because of this, translation by default is no longer working. I will investigate it and try to fix it. Until I manage to come up with a fix, I suggest you give a try alternative translation methods, like Google Translate Premium, which can be enabled by adding your Google Translate API key in the plugin’s ‘Main Settings’ -> ‘Google Translator API Key’ settings field. This will automatically enable the usage of the premium Google Translate API instead of the free one.
However, I hope to fix this issue soon also for the free translation part of the plugin.
