What does Error: This function is currently unavailable error mean?

The error Error: This function is currently unavailable typically indicates that there is a problem connecting to Ubersmith's MySQL server or that your Ubersmith database is empty and/or missing.

If you receive this message, make sure that your MySQL database server is up, and that you have entered the correct login information into Ubersmith itself.

What does the error Database error saving attachment mean?

Your MySQL setting for the max_allowed_packet variable may be too low. By default, the value is 1M (1 Megabyte). You will want to increase this value in your MySQL configuration file (usually /etc/mysql/my.cnf) to at least 16M to allow Ubersmith to properly handle attachments within the system.

What does the error couldn't connect to database: connect failed mean?

The Ubersmith setup wizard cannot connect to MySQL using the information you provided. Not being able to connect to the database could be the result of several situations:

  • MySQL is not running
  • MySQL not accepting connections via a socket (connecting to 'localhost' as opposed to say, '127.0.0.1')
  • The credentials you provided are incorrect, or 
  • The credentials are correct, but privileges have not been flushed.

It may be helpful to troubleshoot your MySQL connection via the 'mysql' command line client, and then retry Ubersmith setup.
