• I just upgraded to version 3.5.2 (which for what I understand allows html content type in emails) but now every time the plugin sends the results of the test to the user and the teacher, it sends it as an attachment of the email, whereas in the previous version it was just a part of the e-mail. Furthermore, the attachment sent is not displaying html.

    I tried doing the fix suggested in the post “Error after upgrading to 2.0.3” but it didn’t work. Can you help me?

    Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, ‘set_html_content_type’ was given in /home/olenad/clubinyaz.com/wp-includes/plugin.php on line 173

    what to do?
    Thanks
