error when adding a new description in view metatag

I have the same issues as above descriped. Since the update of metatag module. The hook where metatag_filter_values_from_default is loaded in metatag module is an array... So rewrite the hook of metatag_views_overview.module to an array.

Also having this problem. Running Meta tag 1.4. The module isn't much use for me unless this issue is fixed, unfortunately, since the reason I need it is so I can set unique meta tags for each display in a view.

Also faced the same problem, the issue was in the line 198 metatag_views_overview.module,
metatag_filter_values_from_defaults($form_state['values']['metatags'], $form['metatags']['#metatag_defaults']);
Here we need to add the language key, the following code worked for me:
// Get default language.
$default = $form['metatags']['#language'];
// Cleanup the metatags.
metatag_filter_values_from_defaults($form_state['values']['metatags'][$default], $form['metatags'][$default]['#metatag_defaults']);

Attaching a patch for it.

Thanks for the patch. It works like a charm.

#3 patch worked, thx [D7.41; Metatag 7.x-1.8].

I would suggest the issue title be adjusted as I had the same issue when adjusting the 'title' field. So maybe something like "error on save with View metatag 'Override View'".

Confirming that this patch fixed the issue in question.

Hi,

#3 patch worked, thx [D7.43; Metatag 7.x-1.14].

Can this be commit it?

Kind regards
