cPanel interfaces

cPanel interfaces can include HTML, Template Toolkit, PHP, or CGI files. 

• Store plugin interface files in the /usr/local/cpanel/base/frontend/theme/ directory, where theme is x3 or paper_lantern.
• Access these files from https://example.com:2083/frontend/theme/filename, where example.com is the domain or IP address, theme is x3 or paper_lantern, and filename is the interface file‘s name.

For example, if you create a custom Support interface in a customsupport.html file, use the following locations:

• Store the file in the following location on the server: /usr/local/cpanel/base/frontend/paper_lantern/customsupport.html
• Access this file at the following URL: https://example.com:2083/frontend/paper_lantern/customsupport.html
