Community Q&A
Why are my Ninja Forms changes not appearing on the live site?
This is typically caused by server-side or plugin-based caching. Clear your site cache and purge your CDN to ensure the latest version is served.
Why are my Ninja Forms emails not sending?
Email issues are usually due to missing SPF records in your DNS or lack of an SMTP plugin. Ensure your domain has a valid TXT record for SPF.
Can theme conflicts break Ninja Forms?
Yes, poorly coded themes or page builders like Visual Composer can cause script conflicts that prevent forms from rendering or submitting correctly.
