Why am I getting the error "Collection with this URL already exist" when trying to make changes in page settings on Webflow? I have a page with slug "blog" and a CMS collection with slug "blog", and my structure looks like '…' and '…'. I haven't changed the slugs.
TL;DR
- Identify the conflict by checking if both a static page and a CMS collection use the same slug (e.g., /blog).
- Resolve it by renaming either the static page slug (e.g., /blog-home) or the CMS collection slug (e.g., /articles).
- Publish and test to confirm the issue is resolved and all links function correctly.
The "Collection with this URL already exists" error occurs in Webflow when a static page and a CMS collection page share the same slug. In your case, both a static page and a CMS collection are using the slug "blog", causing a conflict.
1. Identify the Conflict
- Check your Static Pages: Go to Pages Panel (P) and look for a static page named "Blog" using the /blog slug.
- Check your CMS Collections: Open the CMS panel and verify that the Collection URL is also set to /blog.
2. Resolve the Conflict
To fix this issue, either:
- Change the slug of the static page: Rename the Blog page’s slug to something different like /blog-home or /blog-main.
- Change the slug of the CMS collection: Modify its slug to /articles or /blog-posts in the CMS collection settings.
3. Publish and Test
- Click Publish and check if the issue is resolved.
- Ensure that all page links reflect the correct structure.
Summary
The error occurs because Webflow does not allow a static page and a CMS collection to share the same slug. You need to rename one of them to resolve the conflict.
