[Resolved] WPML Settings Issue: Language Preference for Admin Interface Not Respected Due t

Problem:
If you're experiencing an issue where the admin interface language does not change according to your user settings when the Nextend Social Login plugin is activated, we have identified a conflict that may be causing this.

Solution:
First, locate the following hook in the Nextend Social Login plugin code:

add_filter('nsl_redirect_uri_override', array(
                'NextendSocialLoginAdmin',
                'WPML_override_provider_redirect_uris'
            ), 10, 2);

This hook uses the function 'WPML_override_provider_redirect_uris' which may not generate language-specific URLs correctly. A temporary workaround is to change a line in this function from:

$languageCodeWasOverridden = true;

to:

$languageCodeWasOverridden = false;

However, we have consulted with our compatibility team and confirmed that the issue seems to be a bug in Nextend Social Login. We recommend reaching out to the Nextend Social Login authors to report this problem. Additionally, ensure that you have followed the necessary configurations for compatibility as outlined in their documentation:
