Sudden Cusotmer Login Issue

All of a sudden customers are having login issues. Worked fine for me at work then tried at home and was able to see the issue myself. It just keeps asking you to login even when you enter your correct email and password.

Any ideas as to what can be causing this?

I'm running the latest Zen Cart 1.3.8a

This just started to happen last couple of days.

A little more info, tried to login using IE, Google Chrome, Safari and was NOT able to….Firefox however let me login?

I am having the same issue. Could log in on the 2nd March, not afterwards.

I have tried using IE, Firefox and Chrome. Unable to do t with any of them.

Even tried at work via their proxy servers and no joy.

Even the password resend is saying I have entered the wrong email address.

Any help will be appreciated by me and everyone else with this issue.

Generally when your site works fine, then suddenly doesn't, it's because your hosting company made some change in their server configuration. I would ask them first if they changed anything around that time.
