After hosting my site, I encountered an error 0. I don't know how to fix it and I have to show the site to the owner tomorrow.

I need someone who can guide me through.

I guess the issue is as a result of a line in your code that has been hard coded with an absolute file path that is specific to your local development machine.

Possible Solution
Try to locate the line in your code (I advice you start from your index.php) where you have the absolute file path
"C:\wamp\www\numac2/templates/shaper_awetive/less/master.less"

and then replace it with relative file path (which should work on both your local development machine, and on any computer the code is hosted)

"./templates/shaper_awetive/less/master.less"


Good luck
