Email log view type error

Hi Yehudah,

Thanks again for all your hard work on this plugin!

Everything seems to be working, but just in case you are not aware of this –?I’m seeing some type errors on the email log page in debug. The following are printed before output:

Warning: implode(): Invalid arguments passed in …/plugins/post-smtp/Postman/PostmanLogFields.php on line 53

Warning: json_decode() expects parameter 1 to be string, array given in …plugins/post-smtp/Postman/PostmanLogFields.php on line 61

and the first one is repeated in the log table before each instance of the email subject:

Warning: implode(): Invalid arguments passed in …/plugins/post-smtp/Postman/PostmanLogFields.php on line 53 [subject]
