I’ve given up on waiting for help on this problem from 7theme. You are now saying that the problem lies within woocommerce. However, you provide style sheets and other support for the woocommerce plugin that should provide the capability to modify woocommerce styles. The claim that the thene is woocommerce compatible is apparently not true.
To address the issue, I have made changes to my theme color scheme to correct the problem with text readability. I really didn’t want to make that change, but it seems I have no choice since 7theme doesn’t have a solution to my problem.
