Troubleshooting HubSpot website and page builder issues requires a systematic approach to identify and resolve common technical problems. Whether you're dealing with content editor malfunctions, page loading errors, or form integration failures, the solutions often involve checking basic settings, verifying embed codes, and testing across different environments. The most frequent issues include content not saving or displaying properly, 404 errors on published pages, form submission failures, and editor loading problems—many of which stem from browser conflicts, template incompatibilities, or incorrect configurations.

Key findings from the sources include:

• Content Editor Issues: Duplicate browser tabs, network restrictions, or template conflicts can prevent changes from saving or pages from loading ^[1][2].
• Page Unavailability: Problems like "page unavailable" errors often relate to slug caching, DNS misconfigurations, or language settings ^[4].
• Form Malfunctions: Embedded forms may fail due to missing tracking codes, conflicting plugins (especially in WordPress), or domain restrictions ^[3][8][9].
• Browser-Specific Fixes: Clearing cache, disabling extensions, or switching browsers resolves many display and functionality issues ^[5][7].

Common HubSpot Website and Page Builder Issues and Solutions

Content Editor and Page Loading Problems

The HubSpot content editor and page builder can encounter issues ranging from frozen interfaces to unsaved changes. These problems often stem from browser conflicts, template errors, or network restrictions. Start by isolating the issue to determine whether it’s editor-specific, template-related, or environment-based.

For editor freezing or not loading, follow these steps:

• Close all duplicate HubSpot tabs in your browser, as multiple sessions can cause conflicts. Copy any unsaved content, then reload the editor ^[1].
• Clear your browser cache and cookies, or test the editor in an incognito window to rule out extension interference. Users in community forums report this resolves ~60% of loading issues ^[2][7].
• Switch browsers (e.g., from Chrome to Firefox) to identify browser-specific problems. If the editor works in one browser but not another, disable extensions like ad blockers or privacy tools ^[5].
• Check your internet connection by switching to cellular data if on a restricted network (e.g., corporate Wi-Fi). Mixed-content warnings may appear if external assets use HTTP instead of HTTPS ^[1].

For template or theme-related issues, where changes aren’t reflected or the editor crashes:

• Create a new page using the same template to test if the issue persists. If the new page works, the original may have corrupted data ^[2].
• In Design Manager, right-click the problematic module and select "Lock" to prevent accidental edits. Trigger a re-render by making a minor change (e.g., adding a space) and saving ^[1].
• Contact the theme developer for updates, as outdated templates can conflict with HubSpot’s latest editor versions. One user resolved invisible content by updating their theme ^[6].

If published content disappears or shows a 404 error:

• Verify the page is published (not in draft mode) and check the URL slug for typos or special characters. Temporarily changing the slug and reverting it can clear cache-related issues ^[4].
• Ensure no redirects are broken or pointing to deleted pages. Use HubSpot’s URL Redirects tool to audit redirects ^[1].
• Confirm DNS records are correctly configured, especially if using a custom domain. IT teams should verify A and CNAME records match HubSpot’s requirements ^[1][4].

Form Integration and Submission Failures

HubSpot forms embedded on external sites (e.g., WordPress) or within HubSpot pages frequently face issues like non-functional fields, missing submissions, or complete failure to load. These problems typically arise from incorrect embed codes, missing tracking scripts, or host platform conflicts.

To diagnose form display issues:

• Open the form’s standalone URL (e.g., https://forms.hubspot.com/your-form-id) in a new tab. If it loads here but not on your site, the issue lies with the embedding process ^[8].
• Re-embed the form code by copying a fresh snippet from HubSpot’s form editor. Use a tool like Diff Checker to compare the old and new codes for discrepancies ^[9].
• For WordPress sites, disable plugins one by one to identify conflicts. Common culprits include caching plugins (e.g., WP Rocket) or security tools (e.g., Wordfence). The official HubSpot WordPress plugin often resolves compatibility issues ^[3].

For submission or tracking problems:

• Ensure the HubSpot tracking code is installed on every page where the form appears. Without it, submissions won’t log to your CRM ^[9].
• Add your external domain (e.g., yourwebsite.com) to HubSpot’s Additional Domains list under Settings > Website > Domains. This prevents forms from being flagged as spam ^[9].
• Test submissions in multiple browsers with extensions disabled. Browser privacy settings (e.g., Safari’s ITP) may block HubSpot’s cookies, preventing form tracking ^[8].
• If submissions aren’t creating contacts, check the form’s Follow-Up Options to confirm the correct thank-you message and contact creation settings are enabled ^[8].

For host-specific platforms like Squarespace or Wix:

• Squarespace may alter HubSpot’s embed code during paste. Use the Code Block instead of the standard embed option to preserve the script ^[9].
• In WordPress, avoid editing the form code in the Classic Editor’s "Text" tab, as it can break the script. Use the Custom HTML block in Gutenberg instead ^[3].
