I don't have permission to do this, but IMO 🐛 Error when added to 404 pages Postponed: needs info should be re-opened and this issue should be closed. The bug described there hasn't been fixed.
With this module installed and using the default page.404 config used (an empty string), going to a URL that causes a 404 error makes Drupal throw a fatal PHP error (The website encountered an unexpected error. Try again later.).
With 7.0.x of this module, the specific error is:
Symfony\Component\Routing\Exception\ResourceNotFoundException: No routes found
Drupal\Core\Url::createFromRequest() (Line: 184)
Drupal\better_exposed_filters\Plugin\BetterExposedFiltersWidgetBase->getExposedFormActionUrl() (Line: 74)With 7.1.x of this module, the error is:
InvalidArgumentException: The user-entered string '' must begin with a '/', '?', or '#'. in Drupal\Core\Url::fromUserInput() (line 216 of core/lib/Drupal/Core/Url.php).
Drupal\better_exposed_filters\Plugin\BetterExposedFiltersWidgetBase->getExposedFormActionUrl() (Line: 117)/admin/config/system/site-information and ensure the setting is empty./something-something-something-we-win.The PHP error is being thrown from the code in Drupal\better_exposed_filters\Plugin\BetterExposedFiltersWidgetBase::getExposedFormActionUrl().
Fix this in both the 7.1.x branch and 7.0.x branch.

The MR is for 7.1.x. I've attached the patch for 7.0.x.
Thank you, this patch helped me stay on version 7.0.5 as 7.1 branch is causing other problems on my site.
