Mark,

my database **was** already on utf8mb.

I checked with the server (with the problem) from which I moved to a new server, the sam issue. Server 1: SHOW FULL COLUMNS FROM hyperkitty_email; +-----------------+--------------+--------------------+------+-----+---------+----------------+---------------------------------+---------+ | Field | Type | Collation | Null | Key | Default | Extra | Privileges | Comment | +-----------------+--------------+--------------------+------+-----+---------+----------------+---------------------------------+---------+ | id | int(11) | NULL | NO | PRI | NULL | auto_increment | select,insert,update,references | | | message_id | varchar(255) | utf8mb4_general_ci | NO | MUL | NULL | | select,insert,update,references | | | message_id_hash | varchar(255) | utf8mb4_general_ci | NO | MUL | NULL | | select,insert,update,references | | | subject | varchar(512) | utf8mb4_general_ci | NO | MUL | NULL | | select,insert,update,references | | | content | longtext | utf8mb4_general_ci | NO | | NULL | | select,insert,update,references | | | date | datetime(6) | NULL | NO | MUL | NULL | | select,insert,update,references | | | timezone | smallint(6) | NULL | NO | | NULL | | select,insert,update,references | | | in_reply_to | varchar(255) | utf8mb4_general_ci | YES | MUL | NULL | | select,insert,update,references | | | archived_date | datetime(6) | NULL | NO | MUL | NULL | | select,insert,update,references | | | thread_depth | int(11) | NULL | NO | | NULL | | select,insert,update,references | | | thread_order | int(11) | NULL | YES | MUL | NULL | | select,insert,update,references | | | mailinglist_id | int(11) | NULL | NO | MUL | NULL | | select,insert,update,references | | | parent_id | int(11) | NULL | YES | MUL | NULL | | select,insert,update,references | | | sender_id | varchar(255) | utf8mb4_general_ci | NO | MUL | NULL | | select,insert,update,references | | | thread_id | int(11) | NULL | NO | MUL | NULL | | select,insert,update,references | | | sender_name | varchar(255) | utf8mb4_general_ci | YES | | NULL | | select,insert,update,references | | +-----------------+--------------+--------------------+------+-----+---------+----------------+---------------------------------+---------+ 16 rows in set (0.004 sec)

This looks fine, too, doesn't it?

How can I fix the Internal Server Error? Lost.....
