After create 3 sites,app not work any more

Web Scraper version: 0.3.3
Chrome version: 63.0.3239.84
OS: Windows 10

After create 3 sitemaps,then click console happened nothing,

Developer Tools did not show any error message
developer tools capture

Console hanged click anywhere no reaction
Chrome console hang

So the problem is that you cannot create new sitemaps or these sitemaps don't work as expected?

can not create new sitemaps and can not use created sitemaps scrape data.

I re-install the chrome extension & upgrade chrome ,work well for now.

That's good! Probably you had some issue that was fixed in the latest release.
