Oklahoma Gas & Electric Website

Rcvd an email that my OG&E bill was ready at oge.com. Went there. Obviously a new site since last month. Try to find my bill. Billing statement and history was blank. Called OG&E and was told that it was either the firewall on my computer or Cox's security certificate was not current. Turned off firewall, still no statement. OG&E rep then said it must be Cox. Said she has had lots of calls from Cox customers and that a letter had been sent to Cox regarding this problem. I wonder what the real problem is as I have never had this problem at any other website. Any ideas?
