HI

I have a cisco UC520 that is driving me crazy. On Friday I could access the Cisco Unified Communication Express via the web interface. Now on Monday I keep getting the error of Error: Unable to login as administrator to the Cisco CallManagerExpress at site 'local'.
Details: CME login failed whenever I click on Configuration > extensions or phones. If I click on Users I get access. I did not perform any updates over the weekend. The directory of the flash is listed

Cisco Unity Express Version 7.0

Any Ideas?

Thanks
