When trying to access my site the following error appears twice
Warning: mysqli_query(): MySQL server has gone away in /storage/ssd4/524/954524/public_html/wp-includes/wp-db.php on line 1877
I have the same problem but i resolved it. The error its because your mysql version its not a stable version, you should update your mysql.
