Access denied for user 'wordpress'@'localhost'


After plugin download and activation everything looks fine but the historica data is not saved due to DB access issue. Is this a known issue? How to fix it?

WP DB Error: [1044] Access denied for user ‘wordpress’@‘localhost’ to database ‘wordpress’ SQL: CREATE TEMPORARY TABLE wp_matomo_logtmpsegment2033517e8ca4cfad744d9b5b7bed906e (idvisit BIGINT(10) UNSIGNED NOT NULL, PRIMARY KEY (idvisit))

@innocraft any idea?
