Invalid operation when trying to access User Guide

When i go to

https://help.comodo.com/topic-173-1-415-4603-Introduction-to-Comodo-LoginPro.html

all my browser displays is

“invalid operation”

But no LoginPro User Guide.

Makes me wonder how reliable this service might be, when even the links on the website don’t work properly?

Can you point me to the User Guide?

Hi and welcome Ciprius,
Sorry the support help link from the product page is broken, I will report this for you.

Try the following link.
Introduction to Comodo LoginPro

Thank you.

This is the proper link when using https: Comodo Help .

I learned something new. I didn’t know the online help references are also on https.
