Hello, Greetings! of the day. As mentioned in project description, your author database is unable to record new information about your authors, since a recent update to your server. Assuming, that your application, to save data in database, is using PHP, there may be PHP version update on your server. Due to this, there may be error in your code, used to save data in database. Or there may be some database issue, which will need to be checked on server.
I have much experience in working on projects, using PHP, MySQL. I have much experience in resolving database issues. Your work will be done, at the earliest, according to requirements.
Thanks.
