Hi Albert
The error has nothing to do with BPF as you have the same issue on home page.
I didn't want to ask you to enable HTTPS. Instead, I think you are using HTTPS for BPC URL.
What URL are you using now for your BPC web client?
e.g. http(s)://hostname:port/sap/epm/bpc/web/
Also, are you getting the warning below when accessing the BPC web client?

Clik here to view.
Best regards,
