WHMCS Provisioning and WHMCS WP Integration seem to work but page with shortcodes don't do anyt

I followed all instructions for both of these plugins, and the integration seems to work. I can sue a shortcode on a page and the WHMCS icons and links show up, but clicking on any link does nothing. I can successfully test the actual client portal in WHMCS and all products and links work.

What could be my issue?
