Migration of wordpress database from mariadb 10.0.20 to 5.5.50

I have been struggling with this one and cannot find an answer. I am not an expert with databases and had an issue that is a pain.

I am attempting to migrate a wordpress database to a different server host. The current MariaDB version is 10.0.20 and the new one is 5.5.50

I used phpmyadmin to dump the database I imported it to the new host and got this issue.

I resolved by following the sollution to use MYSQL40

Then trying again I got an issue with TYPE=INNODB.

https://stackoverflow.com/questions/9620439/syntax-error-when-running-a-mysql-create-table-statement

Found the solution and changed TYPE=INNODB to ENGINE=InnoDB in the dump.

Now I get this error and I have no idea how to resolve and found nothing useful

Warning in ./libraries/dbi/DBIMysqli.php#252

Hopefully someone might have a suggestion. Thank you
