Hello @cris88 , @Abhay117 ,
How many other customization you already did in theme ?
If you did then first revert them and then try the code. Alternatively check the conflicts manually and try to fix them.
For those to whom this code is not working.
Once please check the comment day I made and check what version of Dawn was available on that day and what version of Dawn theme is available in these days.
If you find difference then maybe there is chance that theme author made a update in this version and the solution I provided is not compatible with new version. So I suggest just take the idea from my solution and implement it in the version you are using.
