Web Address configured in your RW project doesn't match the published domain?
An error message will be displayed on the published CMS Admin pages when the domain configured inside the RapidWeaver project does not match the domain of the website. This includes www subdomains.
The Web Address setting can be found inside your project settings:
We are in 2015 and browsers are starting to lock down cross domain calls for security reasons. This means that joeworkman.net and www.joeworkman.net are not considered to be the same.
If you want to use the www subdomain, then I suggest that you setup a redirects so that your website always resolves to the same exact domain name. Most hosting companies offer this as a feature. Please contact them if you need assistance setting that up.
