Goto phpmyadmin from your cPanel, open your WP database , go to the wp_options table and edit the site url there. This should fix your problem.
The problem is that you have moved to your new domain but the files are being loaded from your previous domain and therefore it is encountering 404 error trying to fetch the files.

Are you using Shared Hosting? Who is our host?
Some hosts disable tye php.ini configuration for individual sites on shared servers so editing it won’t make a difference if it is tye case. Try contacting your host. They’ll be able to assist you better.

Update : The problem is only there on the desktop version of my site, everything is working fine on mobile version.

Hi,
Try disabling all the plugins and reinstalling the theme. If it get’s fixed then you can enable your plugins one by one to see which one was causing the error.

A plugin named Crayon Syntax Highlighter was causing this issue.
Does somebody know if I can fix it?

Hi!
Just backup your MySql database into a .sql file , then dump it into the database of your other site.
Just be sure that the database in which you are dumping the .sql file is empty.

But won’t it mess up with the oter settings which are there in the old database?

Resolved the problem with my Host.
Thanks for the help

Disabling Jetpack fixed the problem.
But the solution to use Jetpack didn’t work
I changed the max memory limit to 128M in both wp-config.php and php.ini but still can’t use jetpack.
Please help

Hey,
Thanks for the Quick reply.
In my php.ini file I have changed the memory limit from 64M to 128M
But still this error is showing.
Sometime before when I installed jetpack it worked just fine but why not now?

Dude , I think the Migration process of your domain didn’t complete successfully.
I can clearly see that the NS Records of your nameservers are Missing.
Try adding them manually by editing your DNS Zone File.
You will have to contact your Hosting Provider to get this issue fixed.
