How can I resolve the recurring 500 error when reloading one of my two websites on Webflow while the other one does not encounter this issue?

A 500 Internal Server Error on one of your Webflow websites typically indicates a server-side problem related to that specific project, not your browser or connection. Since your second site loads correctly, the issue is isolated to one site.

1. Check for Broken CMS References

• Open Webflow Designer for the problematic site.
• Go to the CMS Collections and check if any of the fields reference deleted assets or references.
• Inspect pages that use dynamic content or Collection Lists. A missing CMS item can cause rendering failures.

2. Examine Page Load Components

• Review custom code in the Page Settings (before or ) of pages causing the error, especially external scripts that might not be loading.
• Remove or comment out custom code temporarily to see if the error disappears.
• Test if a specific page causes the 500 error or if it occurs globally across the site.

3. Disable Custom Code at the Project Level

• Go to Project Settings > Custom Code.
• Temporarily remove any embedded HTML, CSS, or JavaScript, then publish the site again.
• Check if the error persists after removing it.

4. Re-Publish the Website

• Click “Publish” to selected domains from the Webflow Designer or Dashboard.
• Errors sometimes occur due to unpublished recent changes. Republishing forces a clean build.

5. Clear Conflicting Redirect Rules

• Go to Project Settings > Hosting > 301 Redirects.
• Look for incorrect or circular redirects that might be triggering a 500 error.
• Delete or fix any misconfigured redirect entries and republish the site.

6. Reduce Asset Load or Script Conflicts

• If the site loads large videos, custom fonts, or third-party embeds (like calendars, booking widgets), consider temporarily removing them.
• Large or badly formatted assets can sometimes cause servers to fail rendering.

7. Contact Webflow Support

• If the above steps don’t resolve the issue, contact Webflow support with:
• The affected site’s URL
• The specific pages returning the 500 error
• A summary of what you've already tried

Webflow logs internal server-side errors, and their engineering team will be able to identify the root cause.

Summary

A 500 error on one Webflow site (but not the other) is often caused by broken CMS references, faulty custom code, or redirect misconfigurations. Start by isolating dynamic content issues and stripping back to a clean version of the site, then gradually reintroduce elements to identify the cause. If unresolved, contact Webflow Support directly.
