Could this be caused by using Auto-Tables?

Some of the Table objects in your application were created by instantiating "Cake\ORM\Table" instead of any other specific subclass.

This could be the cause for this exception. Auto-Tables are created for you under the following circumstances:

  • The class for the specified table does not exist.
  • The Table was created with a typo: $this->getTableLocator()->get('Atricles');
  • The class file has a typo in the name or incorrect namespace: class Atricles extends Table
  • The file containing the class has a typo or incorrect casing: Atricles.php
  • The Table was used using associations but the association has a typo: $this->belongsTo('Atricles')
  • The table class resides in a Plugin but no plugin notation was used in the association definition.

Please try correcting the issue for the following table aliases:

  • Publishing.TemplatesPageContent
