Bitnami WordPress Multisite is now configured with a domain by default

Have you ever seen the following message when trying to access your different domains in WordPress Multisite?: “ERROR: Cookies are blocked or not supported by your browser. You must enable cookies to use WordPress.”

This is a common issue in some of the most popular browsers such as Google Chrome and Safari. This error occurs when you use an IP address to access your main site in WordPress Multisite instead of using a domain name. By default, Bitnami have placed a transparent domain in its WordPress Multisite stack so you can easily access and work with your domains and subdomains without any issues.

When do you get this error?

WordPress Multisite requires you to have different domain names for each site. If you haven’t this configured, and you are trying to access the administration dashboard by using the IP address, you will get the following error message:

ERROR: Cookies are blocked or not supported by your browser. You must enable cookies to use WordPress.
