Can't create page with the same slug as CMS collection

I have a page with slug “blog” and CMS collection with slug “blog”.
And my structure looks like ‘’ and ‘’.
It was working, but now I get an error “Collection with this URL already exist” and can’t make any changes in page settings.
I didn’t change slugs. Why I got this problem?

Here is my public share link: LINK
(how to access public share link)

Same problem here.
This problem just came up today… Before today this was possible…

I also get this error (“Collection with this URL already exists”) when I want to use a url that I once used but was renamed a few hours ago.
In my example I created a CMS Collection with the url ending of “programm” and changed it to “konzerte”, now I can’t even create a page or folder called “programm”, even if there is no CMS Collection using this URL.

Is this a bug?

Okay I just fixed it somehow, but only to a certain point…
Fist I unpublished my site, then I renamed most of my pages and CMS Collections and then renamed them to the exact same names they had before.
After That I published the site again and I was able to create pages and folders with the wanted name.

But now when I open the folder that I just created it showed me the error message again. So as long as I dont have to change anything on the folder settings, I should be good to go :smiley:

I have had the same issue before but have figured it out with a new website. I created a new CMS collection with a slug like /installation-in/ and then also created a page called /installation-in/

I had not published either the webpage or the CMS at this point. It allowed me to create the page after I created the CMS collection and it all worked fine.

I tested it out and it seems to work fine. So like Martin said maybe it is to do with pages not being published first or around renaming.
