I have a strange problem since a few weeks: If I want to login on my client website I need to login twice. After the first login attempt it says: “Error: Cookies are blocked or not supported by your browser. You must enable cookies to use WordPress.”, then if I try to login again, it works and I am logged in.
I am experiencing the same problem with multiple browsers, with all browsers I am using, cookies are enabled.
I also emptied my browser cache in Chrome but with no avail.
Does anyone know what this problem is and how I can solve this?
