Woocommerce URL problem

I’ve got a weird problem with the URL permalinks when woocommerce is activated.

It just happend after the most recent Woocommerce update. I had normal URL’s and then afterwards it now adds on /?v=3e8d115eb4b3 to the end of every URL.

If I deactivate Woocomers, problem goes away. I’ve tried doing some URL rewriting in the .htaccess but just ends up going in a circular loop if I try to get rid of it.

I’ve searched for an answer but can’t find anything like it.

PS – I’ve disabled W3 Total Cache and any other caching plugins just to make sure it wasn’t sending to a cached page or something. That’s not the case.

Any ideas? Please help
