Hi, @gvectors-team
Thanks a lot for your prompt reply.
Performed as were prescribed. First issue (with empty tooltip) gone after disabling everything except woocommerce and woodiscuz, then found conflicting plugin enabling them one-by-one (it was WOOF – WooCommerce Products Filter, if anyone cares ?? ). So this is solved.
Unfortunately no result on unlimited voting possibilities for unregistered users even after deleting cache, disabling everything and then enabling only woocommerce and woodiscuz. Also tried from different devices and browsers that never been visited my website before, same result achieved.
Maybe any other suggestions?
