Why my URL has an unknown character string?

Thanks for the reply, problem solved !

It was in the Woocommerce general settings “Default customer address”. Had it set up on “geolocalize users with cache support”. Just changed it and v=hash disappeared.

Hata!: SQLSTATE[HY000] [1045] Access denied for user 'divattrend_liink'@'localhost' (using password: YES)
