Hello Abdulaziz,

Kamailio gets during compilation some default configuration path, which might 
point to the old (wrong) location. Have a look to the 'kamailio -f' output to 
see its default, you can also use the '-f' parameter to change this location. 
You get all parameters with 'kamailio -h'

Then try again with the debugging method you choose above.

Best regards,

Henning
