We have now done the update, and this has fixed the issue so thanks to all that replied.
While the new uStore version is all up and running perfectly, we are now on an older version of uProduce.
Could someone please point me in the right direction for getting the update files for uProduce. The UI doesn't appear to have an upgrade area like the uStore site.
I can see the downloaded uProduce installer sitting on our server from a previous upgrade, but this was carried out by xmpie for us, so I don't know where to download the latest installer or where to get instructions and help on carrying out the upgrade.
Thanks
