I install the integrity Theme and activated it as my basic theme.
I become this error message:

Warning: array_flip(): Can only flip STRING and INTEGER values! in Drupal\Core\Entity\EntityStorageBase->loadMultiple() (line 232 of core\lib\Drupal\Core\Entity\EntityStorageBase.php).

I use Drupal 8.0.2

@Bernsch

Your problem is not related with this one, you should open a new issue in the Integrity Theme not here, but looking in your issue, the problem is to you need to set images for the slideshow :-)

I have the same issue

array_flip(): Can only flip STRING and INTEGER values! in Drupal\Core\Entity\EntityStorageBase->getFromStaticCache()

After a migration from D6>D8
All Forum articles have been migrated "successful", also the forum structure (by taxonomy), but all article have not two fields, "Forum" and "Forums"
where Forum is filled with the migrated Forum title and "Forums" is empty. "Forums" it the D8 entity

It seems to be an issue for the Migrate D6>D8 team?

I've reproduced this issue in testing #2690001: Migrate: Don't deduplicate forum vocabulary - the root problem is migration creating the taxonomy term reference field as "forums" rather than using the existing field with machine name "taxonomy_forums". Let's address this issue as a follow-up to that one.

Dependent issue was committed, this one is open for business.

Version: 8.2.x-dev » 8.3.x-dev

Drupal 8.2.6 was released on February 1, 2017 and is the final full bugfix release for the Drupal 8.2.x series. Drupal 8.2.x will not receive any further development aside from critical and security fixes. Sites should prepare to update to 8.3.0 on April 5, 2017. (Drupal 8.3.0-alpha1 is available for testing.)

Bug reports should be targeted against the 8.3.x-dev branch from now on, and new development or disruptive changes should be targeted against the 8.4.x-dev branch. For more information see the Drupal 8 minor version schedule and the Allowed changes during the Drupal 8 release cycle.

I am unable to reproduce the array flip error. Adding new forum topics is working fine for me. Anyone still having this problem?

The problem of having two forum fields, #10, now has it's own issue, #2864984: Two Forum fields on add forum topic page.
