Hi, I built my website 3 years ago with using the illdy theme. Recently site has not been functioning and theme is not showing up anymore. Been on phone numerous times with hosting company, Bluehost. Also having been on phone several times with security host, Sucuri. Both companies are not able to correct the problem. Bluehost recommended to reach out directly to Colorlib, as you are the theme host. Attached view of what shows up when you go to the site. This has been extremely frustrating and disappointing.
Hi there
Hope you are having a good day and thank you for your question 
please provide url and i will take a look
Good morning
There is nothing wrong with he theme, you have more than 63 internally server error, this means files are not loading from the server, contact to your host and show them this image: Screenshot by Lightshot
