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?
TL;DR
- Check Webflow Status for outages.
- Test on a different network/device and clear cache.
- Disable custom code, republish, and isolate problematic scripts.
- Check CMS limits and remove recently added items if needed.
- Re-publish the site to fix deployment errors.
- Disable third-party integrations to rule out conflicts.
- Contact Webflow Support if the issue persists.
A 500 Internal Server Error in Webflow can occur due to various backend issues, but if only one of your two sites is affected, it's likely related to that project's specific settings, custom code, or server-side dependencies. Here’s how to resolve it:
1. Check Webflow's Status
- Visit Webflow Status to see if there are ongoing outages affecting your site.
- If Webflow is experiencing downtime, the issue should resolve once their services are restored.
2. Test on a Different Network & Device
- Try loading the affected site using a different browser, device, or network to rule out caching or local issues.
- Clear your browser cache and disable extensions to see if that helps.
3. Review & Disable Custom Code
- Go to Project Settings > Custom Code and check the Header Code and Footer Code sections.
- Remove or comment out any custom scripts, then Publish and check if the error persists.
- If the error stops, isolate which script is causing issues by re-enabling them one by one.
4. Check CMS Collection Limits & Issues
- If your project relies on a CMS Collection, check whether it exceeds Webflow’s limits (e.g., items per collection, reference fields).
- Try to delete any recently added CMS items and see if that resolves the issue.
5. Re-Publish the Website
- Sometimes, republishing fixes corrupted assets or deploy errors.
- Go to Designer > Publish > Select All Domains and publish again.
6. Disable Third-Party Integrations
- If you’re using third-party embeds (e.g., analytics, chat widgets, custom JavaScript libraries), temporarily disable them and test if the issue resolves.
- Webflow may be unable to process a certain API request, causing a 500 error.
7. Contact Webflow Support
- If none of the above solutions work, reach out via Webflow Support.
- Provide details such as screenshots, the affected URL, when the issue occurs, and any recent changes you made.
Summary
A 500 error means there’s a server-side issue, often related to custom code, CMS limitations, or Webflow's infrastructure. Start by testing another network, disabling custom scripts, checking CMS collection limits, and republishing. If the issue persists, Webflow Support can investigate further.
