[Plugin: WooCommerce – excelling eCommerce] Woocommerce CSS styles causing 'blank' submit

I apologize if this has been asked & answered, but I have not been able to find any related threads.

I’m using Woocommerce with Inktheme’s Colorway Lite theme – and while I’ve been able to resolve compatibility & styling issues so far, I’ve run into a problem with the Woocommerce CSS settings.

If I check “Enable Woocommerce CSS Styles” I end up with a white rectangle instead of the “Submit” button for Reviews & Comments. If I leave the Woocommerce CSS Styles unchecked, I don’t get the “Description” & “Review” tabs on my products page, which I really like.

How or what can I do to fix the CSS so the “Submit” button is correct?

I’m developing my site on WAMP so cannot provide a link for it. Thanks in advance for the help.

Jean (edit ’cause I’m really tired & can’t spell my own name – have been working on resolving this issue for over a day.)
