I just install and activate it in my website, looks fine.
but after I change the plugin settings and save it, I got this issue :
Warning: explode() expects parameter 2 to be string, array given in /.../wp-content/plugins/google-ajax-translation/ajaxtranslation.php on line 381
Warning: Cannot modify header information - headers already sent by (output started at /.../wp-content/plugins/google-ajax-translation/ajaxtranslation.php:381) in /.../wp-includes/pluggable.php on line 866
sorry about my bad english
