I’d deleted the illdy demo content somehow and now I’m trying to build a homepage with this theme. While customizing the front page sections I cannot control the jumbotron section. I upload my background image as the cover image for this section but it isn’t published as it should be. Moreover, I cannot install the demo content. I’d be glad if you help me about this subject as soon as possible.
Hi there
Hope you are having a good day and thank you for your question 
You can reet current installation if you want to start over and start with demo content,
if you want to use existing installation then i can help you bu i need access details to your website to check why it’s not working, so, please post them here and use set as a private checkmark
Thanks!
