Have you tried this: When you move your mouse above PE's quick-connector you'll see in the right corner above three dots. Click on those and you'll be able to change the url.
With me it worked.

I can't see the possiblity to change the URL.

This is starting to happen to me when I try to access the site through a web search, as opposed to my saved link for the website.

Problem is over, because I have a new computer. Not really a fun way to get rid of some minor problem with a website, but alas my computer didn't start at all and kept showing the opening-screen and at that point nothing worked. Press Del or F2 to go to BIOS setup, forget it.
