With the new cpanel & Litespeed upgrade, we are facing "403 Access Denied" issues on some addon domains and subdomains. Currently, we are working to fix that with cpanel technical team for all users. in the meantime, you can fix that by yourself by changing folder permission to 0755 in cpanel file manager. sorry about the inconvenience.
cPanel provides an easy-to-use interface for setting file permissions within the File Manager. Open File Manager, which you will find in the Files section of the main page.
File permissions are displayed in the rightmost column of the File Manager, using the numerical notation.
To change them, select a file and click Permissions in the menu bar.
