The DatabaseConnection classes have changed.  They now encapsulate a PDO object, rather than extend it.  A scant few modules used the PDO functions in the DatabaseConnection object, including:

  • Backup/Migrate
  • Database SSL Connection
  • All database drivers

Before upgrading to 1.19.0, upgrade these modules to a compatible version or disable them. 

If you use a database driver other than the MySQL that ships with Silkscreen core, make sure you update to a compatible version.  For PostgreSQL and SQLite, use 1.19.0 or later.
