I am having a problem displaying custom options on the product page in Magento. I'm using Modern as the base for my theme, and changing themes doesn't seem to have any effect. The catalog.xml is almost the stock one for the theme.
When viewing the page, I get the message "Please specify the product's required option(s)." but nothing shows up. Additional information that have been added to the attributes show, but no product specific custom options.
Looking with developer hints, I see that /catalog/product/view/options/wrapper.phtml is not appearing on the file. Could something be missing in one of the layout .xml files?
Any idea what might be going on? Thanks!
