* 1. Go to Settings > Permalinks and select any page as home page
* Then use the following code
*
* You can add those codes in your functions.php in the theme, if you think your theme won’t be changed.
* Otherwise mu-plugins is the best solution. To use mu-plugins, go to /wp-content/ and find the folder with name 'mu-plugins'.
* If there is no folder in that name, then create a folder, name it 'mu-plugins', create a file inside that,
* give any name you like and paste the code in there. You don't need to activate that plugin. Mu-plugins means must use plugins,
* so it will be activated automatically always. If you use mu-plugins then add a php start tag at the beginning of the code.
*
* Just change the correct CPT name
