Plugin Stopped working after WP and Woocommerce Updates

I have tried to reindex and clear cache too. But no chance, there is no search results. Please advise.

Rlevenssi Version 3.5.2
WooCommerce Version: 2.4.13

But please note I even disabled the relevanssi still getting no result. I don’t know what is going on.
