I had the same problem. It worked int 5.7.6 with one install. I did another install and the option sets did not work. I tried the update
listed here… http://quirm.net/forum/topic.php?id=1970
but it still failed.
I found the table XXX_eshop_option_names was missing. After I copied it from another install it worked fine…
Hope this helps.
Thanks Rich for all your hard work.
