after a recent update an site movement the following stopped working.
I already used some hours to find the error.
When somebody subcribes, he wont get a confirm-email although email-sysstem is working.
I found the problem in the subscription.php in the function “subscribe” where “$options” should load the “newsletter”-option-array from the wordpress-database. There is (the correct?) data in the database, but “$options” gets only a “1” so nothing afterwards works at all.
The Mail in line 310 is not send, only if i customize the “subject” and “message” strings.
