I have a client that when they try to log into their dashboard they get a message on the log in page stating that they must enable cookies. They walk through the enabling process, whether the cookies are already enabled or not, and are able to log in. However, if they close out, they have to enable cookies again to log in. Now, they are using an older computer and browser. My computer logs in with no issue, but my browsers are all up-to-date. I have advised them to try to download/update FireFox and or Chrome to see if that helps. Is this a browser related issue or WordPress?
