Hello and thanks for looking into it
We have moved the store online so you can access it now, here is a link where the issue happens.
If you want to recreate the issue you can type either on the search bar and click on the only product that appears.
– Bloke
– Athazagoraphobic
Note that these are just some examples, there are several more products.
An update regarding the issue with the search bar. It was fixed after several reactivation-activation cycle of the Filter Everything Pro so now the only issue is the products returning a 404.
