Why do I see a Red Error Border around my Map?

A red border and error banner around your map in Webflow Designer means Dynamic Map has detected that its internal element structure has been disrupted. This happens when a core Dynamic Map element, specifically any element with a class prefixed with cru-ncf-, has been accidentally deleted, moved out of its expected position, or placed in the wrong location in the Webflow Navigator. The red border is a protective warning signal, not permanent damage. In the overwhelming majority of cases, a single undo resolves it in seconds.

What the Error Looks Like

The error banner reads: “ERROR: Press CMD+Z or STRG+Z to undo your last action. Something you’ve done has broken Dynamic Map for Webflow. Open Dynamic Map App if undoing your last action didn’t work out.”

How to Fix It

1. Undo your last action. Press CMD+Z (Mac) or CTRL+Z (Windows) and check if the red border disappears.
2. If this isn’t possible any more, delete the map and re-create it using Dynamic Map App from scratch.

💡 Diagnostic tip: Check the Webflow Navigator for any cru-ncf- elements that appear in unexpected positions or are missing entirely. This will usually pinpoint what triggered the error.

Practical Tips

• Press CMD+Z (Mac) or CTRL+Z (Windows) first, as that’s the fix in most cases. Think back to your last action in Webflow Designer. The red border almost always appears immediately after a structural change. Undo that action and check whether the border disappears.
• Use the Webflow Navigator to locate displaced elements. If undo isn’t available, open the Navigator panel and look for any cru-ncf- element that appears outside the main cru-ncf-dynamic-map wrapper, or that’s at the wrong nesting level. Dynamic Map elements must stay in their generated positions.
