r/Carrd

My webpage, which is still under development, went completely blank after publishing. This was happening when I started my project, yesterday it decided to show itself and today it happened again. I do not have much knowledge in website development so does anyone have any idea why this is happening? I did check the webpage on different browsers and in incognito mode. I have raised a ticket and am waiting for a response from Carrd about this.

I'm thinking of making an email list for customers who want to know when new stuff will be dropped before they see it on social media.

Is it possible to do that on carrd pro standard plan?
