Hello, the site builder/wireframe tool has glitched for me for the past few weeks every time I try and drag and drop a section. The section or page I'm trying to move will not "lock" into place and will just float around and sometimes go back to where it came from, but other times, it will just get deleted. It is getting increasingly worse. Has anyone else experienced this?

I am unable to get into any of my sitemaps due to a server error. Anyone else having this problem? I've tried refreshing, logging in and out, using a different browser etc.

Can someone tell me why this website won't import into the sitebuilder? Does it have something to do with the XML sitemap?
