All Galleries Vanished

The galleries linked to from https://www.allstarplastics.com.au/gallery/ were working fine until just a few days ago (I think…most recent Google cache I can find is 22 Dec 2020 – the cache shows images. Now when somebody clicks on any of the links on the above page it results in a 404 error.

We are a pro subscriber…not sure if that means we can get more support somewhere.

Many thanks for any advice or help you can offer.
