在PRESTASHOP中的多线程URL上找不到所有CSS和JS文件

I have enabled multistore option enabled in my prestashop website. I also setup a store named 'abc' and set its url 'http://example.com/abc'. My site home page is runnig well but when I go to my store url 'http://example.com/abc' it does not load properly due to it couldn't found all js and css file in head tag and it is showing 404 not found for all css and js file in consol. What can be the problem there.? Thanks for advance help.

1. Open vim config/settings.inc.php from config folder

2. Locate the line that contains the __PS_BASE_URI__ setting, and then update the value with the base URI.

   If you installed PrestaShop in the document root directory 
   (for example, public_html), 
   then the base URI is /. Alternatively, if you installed PrestaShop 
   in a subdirectory, 
   the base URI is /path, where path represents the folder name. 
   For example, the following line shows 
   the base URI set to the document root directory (/):
   
   define('__PS_BASE_URI__', '/');
   
   for subdirectory - define('__PS_BASE_URI__', '/directoryname');
   

3. Save Changes.
