apply_filters( 'relevanssi_update_translations', boolean $update_translations )
This filter hook controls whether Relevanssi Premium tries to get translations from the TranslationsPress service or not.
Parameters
$update_translations
(boolean) If false, Relevanssi doesn’t try to connect to the TranslationsPress server for new translations. Default true.
More information
If your site is only in English or in some other untranslated language, you can disable all connections to the TranslationsPress servers. Add this to your site:
add_filter( 'relevanssi_update_translations', '__return_false' );
This may speed up your WordPress admin somewhat and save bandwidth, as no calls are made to the server anymore.
