Customer Login Problem

[Barry]

Gah! this is happening again for us, not sure what caused or fixed it last time either, all a bit of a mystery

"Sorry, but we found your account but couldn't read the details. This may be because the login page you used is an old copy stored in your browser cache. Press the Browser Back button, then refresh the login page and try again." Im Using v8

Anyone have any thoughts on why this happens every now and then? or how to fix it?

Thanks folks, all the best
