Hi,
Ok we have several issues now, so it might be a good thing your testing the release as such...
We always extensively test the releases before doing them. But we can't see everything. That's why we don't activate the auto update for a few days/weeks after each release so that people can first test them on their end, and when we feel it's stable enough, we activate it, so that people with live websites can also update.
If you have a live website, you shouldn't update Joomla, HikaShop or any extension directly on it.
You should first do it on a test website and when everything is ok for you, you can proceed on the live website.
We can't predict what will break in Joomla releases. So we can only provide patches after the fact.
1. The issue with the link to the product pages seems to come from your canonical URLs which are incorrect in your products. Turn off the "force canonical URLs on listings" and that should fix the problem.
2. The issue on that other thread is that the modules on the right part went under the product page because of a change in the HTML of the product page. I don't see that problem on your product page:
www.nanasweightedblankets.com.au/product.../single-bed-blankets
So I don't understand what problem you have which is similar to what is there ? Did you already fix it ?
On our end, we're currently investigating the issue with the microdata tags for the other thread and we'll reply soon there.
3. I've tested the characteristics switching mechanism on the page
www.nanasweightedblankets.com.au/product.../single-bed-blankets
but it seems to be still working.
Could you explain more in depth what is not working with it on which page ?
