1. Missing page links: https://www.cynamedical.com/product/basic-dental-oral-hygiene-kit-set-of-3/ (this happened when I clicked on the G-pay button which has some problem but at least it should display the notification) and https://www.cynamedical.com/product/cynamed-hartman-mosquito-hemostats-with-multicolor-titanium-coating/ (this occurs with the waitlist woocommerce extension)

2. I can’t take the risk of loose any of my website settings because I did a lot of work on it. There is another thing I can do for you to be able to understand the behavior of this extension (Wocommerce waitlist) which is I made a test website for testing some features, and this is one of them. On this website, the same woodmart theme is installed and the feature of the waitlist extension is working fine. Credentials are below.

3. Why the product label color is not changing from the theme settings?
