blog not working

Site is working but design is not coming perfect.Is that the problem you are getting?

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.

To nreshchd,

Yes,

I tried to change domain name in Site URL & WordPress URL “fitnessforyou”

which is previously shivdasashtekar

and it’s appears problem

When I try to open shivdasashtekar/wp-admin in home page its appear site si not working

To Aakash,

I am unable to login to dashboard so it’s difficult see for plugins

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.

Edit your wp-config.php file and add the following just before /* That's all, stop editing! Happy blogging. */
line:

define('WP_HOME','https://example.com');
define('WP_SITEURL','https://example.com');

Don’t forget to change https://example.com to your original domain.
