Experience Level: Intermediate
We have recently encountered this error message on our Drupal 7 website which uses Ubercart and some custom modules.

The error doesn't seem to break much of the functionality of the website as people have still been signing up and paying through Ubercart. However the autocomplete tagging is not working for 2 content type fields which we think may be related and we are also unable to rebuild access permissions.

The error is as follows

Warning: array_flip(): Can only flip STRING and INTEGER values! in DrupalDefaultEntityController->load() (line 175 of /home/aiuchico/public_html/includes/

Warning: array_flip(): Can only flip STRING and INTEGER values! in DrupalDefaultEntityController->cacheGet() (line 388 of /home/aiuchico/public_html/includes/

Recoverable fatal error: Object of class stdClass could not be converted to string in DatabaseStatementBase->execute() (line 2227 of /home/aiuchico/public_html/includes/database/

We are looking to get this issue fixed as soon as possible and are looking for someone who has hopefully encountered this error before so knows what is causing it and can successfully debug, removing the error and restoring the use of the autocomplete.

We understand the error is quite vague so if you need more information please get in touch.
