Troubleshooting
Visual editor and MCP problems
Fix iframe loading and common AI-assistant connection errors.
If the editor cannot load a page, check public accessibility, authentication, X-Frame-Options, CSP frame-ancestors, bot protection, and mixed-content errors. Use a redirect test when the target cannot safely be framed.
For MCP, verify https://pageduel.com/api/mcp, authorization method, key validity, read/write permission, site scope, and active plan. A 401 is authentication; a permission or site-scope message requires a differently scoped key. Revoke and replace any key pasted into logs or chat.
