Question: I'm trying to create a new Wordpress website in Azure. Today when I get to the page about creating a new mySQL database, I can't check the box to agree to the ClearDB terms - even in the HTML box it's disabled.

Tried this on both US East and US West servers, same thing. Database name meets their requirements, I've done this a few times in the past. No idea why I can't today.

Answer: 
try this:

New -> Store

Data -> ClearDB

After that try to add the Wordpress (New -> Compute -> Web Site ->From Gallery), but instead of create a new Mysql database, use this one that you create in the step above.
