    My newsletter created by Mailpoet 2.7.5 has different Links that are not working. The problem was already known one year ago. Few are okay, but if I click some different:

    WordPress-Datenbank-Fehler: [Illegal mix of collations (utf8_general_ci,IMPLICIT) and (utf8mb4_unicode_520_ci,COERCIBLE) for operation ‘=’]

    Warning: Cannot modify header information – headers already sent by (output started at /www/htdocs/XXXXX/XXXXX.XXX/wp-includes/wp-db.php:1386) in /www/htdocs/XXXXX/XXXXX.XXX/wp-includes/pluggable.php on line 1174

    How do I fix this?

    Fixed the problem by converting the collation of database tables. Although it is a very new site, a plugin put tables with utf8mb4_unicode_520_ci instead of utf8mb4_unicode_ci in my database.
