Hi Annie,
Thank so much for reaching out and thank you for using Crio Pro WordPress theme!
I’m so sorry to hear you’re having problems with your Crio theme, as well as located your Premium Access Key and Premium Support.
One way you can obtain your premium access key is through your BoldGrid Central account. You’d just need to login and navigate to the “Connect Keys” tab and copy your “Premium Connect Key” then paste it into your websites Crio configurations.
We have a guide on “How to find your “Connect Keys” that you may find useful.
Now for your issue of your site being in “Dark Mode”, that is not a native Crio feature so I’m assuming it may be coming from a different plugin or CSS setting. Is this issue only present on the backend (admin) section of your website?
We look forward to hearing from back from you on the last matter. Please let us know if there’s anything else that we can answer for you!
