I recently started encountering an error when trying to delete content nodes, log shows the following errors. Version 7.x.1.7 is installed.
Warning: array_flip(): Can only flip STRING and INTEGER values! in DrupalDefaultEntityController->load() (line 178 of /Users/Patrick/Sites/acquia-drupal/includes/entity.inc).
Recoverable fatal error: Object of class Message could not be converted to string in DatabaseStatementBase->execute() (line 2139 of /Users/Patrick/Sites/acquia-drupal/includes/database/database.inc).
As soon as I disable the module I can delete content no problem.
