Hello @bmrabti,
As you can see, your instance is running out of storage:

This kind of error could be related to WordPress plugins. Some plugins use the MySQL database as temporal storage and they do not properly clean it after that. Can you check your plugins?
If you have big MySQL binlog files, it may mean that you are under a bot attack or any plugins are heavily using the database for temporal storage and it is generating a lot of database events that are logged in the binlog files. Can you check the next guide about bots attack?
https://docs.bitnami.com/google/apps/phpbb/troubleshooting/deny-connections-bots/
You can also purge the binary logs following this guide https://dev.mysql.com/doc/refman/8.0/en/purge-binary-logs.html
or you can disable https://docs.bitnami.com/aws/apps/wordpress/troubleshooting/disable-binary-logging-mysql/
If after that you still have a problem with space, could you try if resizing the server to solve all the issues? Find below our documentation:

I hope it helps
