CakePHP database table, missing datasource default

Have you checked your database, e.g. in phpMyAdmin or MySql workbench? Does the table exist in the database?

The error message indicates that the table could not be accessed using the default connection. It's possible that the table is really missing, or that the user you're using to connect to the database does not have the right permissions for that table.

If you migrated the database from another server, did you get error messages while importing? If you did not create a dump enclosed in a transaction, it's possible that the database dump was only partially imported.

[update] this suggestion solved the problem;

Remove all files from app/tmp/cache/persistent and /app/tmp/cache/models then enable debugging. Your SQL log/debug should show the queries that CakePhp is using to detect if the tables exist in the database. Also you'll be able to check if Cake writes to the tmp files without problems
