1. My theme is not working
Before anything else, make sure that you are using at least PHP version 5.4.24. Falling into this issue usually ends up with aParse error: syntax error, unexpected T_PAAMAYIM_NEKUDOTAYIM, expecting T_VARIABLE error
Before contacting your hosting company, you might want to check your Cpanel for Select PHP Version
2. My homepage is not displaying the demo sections
As of the latest Illdy versions, the Reading front page display settings has changed from Your latest Posts to a dedicated static front page. To get the site displaying alright, first go to Dashboard > Pages > Add new > Create Home & Blog page. Then head over to Dashboard > Settings > Reading > Select A Static Page > Select Home & Blog page.The blog static page is optional, as you can set the blog page template in the page right attributes panel and it will display directly. This is helpful if you want to control the blog page header title.
3. There is missing content from my homepage
To avoid injecting default information as live content, the demo content only serves as guideline to set up your own widgets information.All the demo content needs to be re-saved/modified/custom/replaced and re-saved to appear on the website while not logged in the Dashboard.
Replacing the missing content with new one will regenerate it on the live website.
4. How do I set up the menu?
First of all, you need to create your own menu in Appearance -> Menu. There, use custom links. Each page section has its own link as written below../#about
./#projects
./#testimonials
./#services
./#latest-news
./#counter
./#team
./#contact-us
Of course, you need to replace dot with name of your webpage. When you are done, save the menu.
Now you need to add this menu to your illdy page, which can be done in Appearance -> Customize. There, in Illdy’s customization menu, click on “Menu”, remove the old one and add your own. (answer courtesy to @pa3kson)

This post was created as a thank you note all for the great interest in our theme and for all the kind words!
Thank you for being so supportive when misconfigurations appeared and for looking to improve your setup and experience with the theme.
I will periodically edit and improve this post to reflect the most common issues, and I kindly ask you to do the same if you find any missing documentation or a common issue, please add it below and I’ll review it up the list.
Happy websites, everyone 
DISCLAIMER: I cannot stress enough about how fine the line is between free theme support, premium theme support and paid support for custom coding. Similar situation for theme related issues, WordPress or some 3rd party solution. In the search for the perfect setup, please ask yourself if your issue needs more theme or dashboard documentation, or if what keeps you from the finished product is related to a bug, a lack of theme functionality, requires custom work and styling or just some guidance. I’m sorry if I don’t get to help with all the requests in the same proportion, but I cannot function as a personal designer in the free support scope. If you feel like your request is a personal custom modification, I will happily provide you a quote for premium dedicated support. But always keep in mind that previous forum posts function as the best source of previous common custom solutions, so it should be the perfect place to start answering those questions.
