I have just installed Illdy and it is not showing the full theme. I am a rookie so I might be making a silly mistake.
Here is a screenshot
Hello @himanshu,
It seems like you still have to set the front page display in Dashboard > Settings > Reading to a Static page that you previously created in Dashboard > Pages.
With this in mind, it seems a little strange though that you get a 404 not found page, so you might want to save the settings again in Dashboard > Settings > Permalinks.
If nothing of the above gets your issue fixed, please consider to provide me temporary admin dashboard access via a private message so I can live investigate the installation.
Regards
