Please post your SR number. I'd like to take a look at some of the log files.
Was there a fix to this without support's involvement? I'm running 7.07 and just encountered this same error this morning. I hadn't had to create a new scan template in a while and when I clicked on optimize and then tried to proceed I encountered the exact same web optimization error and I couldn't proceed. For the time being, I just copied and existing template and modified the copy for my needs. For creating a new scan from scratch gave me this error.
