Finalsite CMS Error Codes Guide

This article covers errors and system messages in Finalsite CMS (Composer), including platform access errors, content errors, file upload failures, form payment issues, messaging delivery errors, and account data errors. 

💡 Quick answers

  • How do I diagnose a site outage? Check status.finalsite.com first. If no incident is posted, contact Finalsite Support with the site URL and time the issue started.
  • What causes "Error in rich text context" in Composer? A single Content element exceeded 75,000 characters. Split content across multiple Content elements.
  • What should be done when file uploads time out? Compress or resize the file. For video, use a YouTube or Vimeo embed instead.
  • What does "Completed (Error)" mean in form payments? The payment was flagged at the processor level. Do not re-run it; contact Support with the form submission ID.
  • Why does a group show the wrong member count? Counts sync on a delay after imports or changes. Wait a few minutes and refresh. If still wrong, contact Support with the group name and the numbers showing.
  • An email says "recipient is in suppression list": what does that mean? The address was previously flagged for a bounce or complaint. Contact Support with the email address to request a review.
  • Why are text messages getting a "screening error" or blocked by 10DLC? Carriers require SMS traffic to be registered under 10DLC. Contact Support to check registration status.

Error types

Every error falls into one of these categories, which determines the resolution path.

Type Description Resolution path
User error Caused by a user action: content, settings, or permissions. A self-serve fix exists. Follow the steps in the linked article. No support ticket needed in most cases.
Bug A platform or code defect. A workaround may exist but there is no full self-serve fix. Use the documented workaround. If none exists, contact Finalsite Support.
Known issue A confirmed bug that Finalsite is actively tracking. Use the documented workaround. Engineering is working on a fix.
Platform Generated by Cloudflare or another platform layer, not by Finalsite application code. Steps vary. See the linked article for whether this auto-resolves or requires action.

Common HTTP status codes

These status codes may appear in browser error pages or when content fails to load.

Code Meaning Common cause in Finalsite CMS
