Troubleshooting

Symptoms first, in the words people actually use. Every entry links to the page that explains the behaviour properly.

Almost everything here is CheckFlow working as designed. The two genuinely most common causes are a missing permission and a change made to a template after the checklist already existed.

I Cannot See Something

What you see	Why	What to do
No Show Menu button on an open checklist	You do not hold Checklist.Menu	Ask an Administrator. See User Permissions.
The Selected button offers no archive or delete option	Those are Administrator-only bulk actions	See Managing Checklists.
No Archived Checklists entry in Report Views	Administrator-only view	See Archived Checklists.
The Library is empty, or a folder is missing	No Library permission, or Deny on that folder	See Library Roles and Permissions.
A Tag Page shows no library items	Library items need Library.Viewer; without it the section is not shown at all	See Finding Tagged Items.
The activity feed is missing	Not visible to Guest users	See Activity Feed.
A permission was granted but nothing changed	Permissions apply when the user's token refreshes	Log out and back in. See User Permissions.

A Task Will Not Complete

What you see	Why	What to do
Error under a control	A required control has no value	Fill it in. See Control Types.
Cells outlined in red on a table	Required cells are empty	See Table Control.
The task is greyed out	An earlier halt task is not complete	See Enforce Task Order.
The task is greyed out, and you are not an assignee	Only Assignees Can Complete This Task is set	See Task Assignments.
A Mail-To control blocks completion	Send Mode is Required – Manual Send	Send the email first. See Mail-To Control.
A pop-up error when completing from the Dashboard	Validation failed on a control you cannot see from there	Open the checklist and complete it there.

Required table cells are not enforced everywhere

A Table validates its required cells only when the task is completed from inside the checklist. Completing from the Dashboard or through the API bypasses it. If a value is essential, back the table up with a required Short Text or Sub-Tasks confirmation.

My Change Did Not Take Effect

What you see	Why	What to do
Edited a template, existing checklists unchanged	Deliberate — a checklist is a record of what happened at the time	See Templates Overview.
Changed a template's tags, existing checklists keep the old ones	Same rule	See Tagging Templates.
Added a Data Set record, a Sub-Tasks or Table control did not update	Those two capture their list once, at creation; Dropdown and Multi-Choice read live	See Using Data Sets in Checklists.
Changed checklist permissions and it did affect existing checklists	The deliberate exception — access control must apply immediately	See Checklist Permissions.
A template change did not create a new version	Permission changes are the one edit that does not version	See Template Versioning.

Something Sent, or Did Not Send

What you see	Why	What to do
A Mail-To hidden by conditional logic still sent	Hiding affects display only; Auto Send still fires	Use Optional – Manual Send and hide it. See Mail-To Control.
A Mail-To send failed with no valid recipient	A dynamic value in To could not be resolved and was dropped	See Mail-To Control.
An auto-sent email has not appeared in the log	Auto sends are dispatched by a background process shortly after completion	Wait a moment and check again.
The same Mail-To did not send twice	Each auto-sends once per checklist, even if the task is re-opened	See Mail-To Control.
No Is Completed notification when a task was skipped	Marking Not Applicable does not fire it	Anchor on Status Is Changed instead. See Mark a Task Not Applicable.
A user stopped receiving overdue emails	They can unsubscribe in their own user settings	See Task Due Dates.
A CSV import into a Data Set raised no webhooks	Bulk operations deliberately raise no per-record events	See Webhooks API.

Reports and Analytics

What you see	Why	What to do
A control is missing from the column list	Only ten control types can be a report column	See Report Columns.
No Tasks & Fields columns at all	They appear only when exactly one template is selected	Select a single template.
A saved report view cannot be shared	Sharing needs Report.Creator; creating one does not	See Custom Report Views.
Reports and Analytics disagree	They measure different things over different scopes	See the comparison at the top of Reports.

Controls Behaving Oddly

What you see	Why	What to do
An Embed control is blank	The target site blocks being framed — set by that site, not CheckFlow	Try the service's dedicated embed URL. See Embed Control.
An embedded video will not play	The source blocks embedded playback, or the video is private	See Video Control.
A Linked Checklist shows a message instead of the child checklist	Linked Checklists cannot render inside a shared checklist	See Linked Checklist Control.
Auto Create is unavailable on a Linked Checklist	The linked template is the template the control lives in	See Linked Checklist Control.
A tooltip icon does not appear on a Separator	A Separator draws no label for the icon to attach to	Put the tooltip on another control. See Tooltips.
Two tags look identical but behave separately	Two tag objects with the same name	Always pick from the autocomplete. See Applying Tags.

Still Stuck

If the answer is not here, contact support. Include the checklist or template name and what you expected to happen — the difference between "it did not work" and "the task would not complete and there was no error" is usually the whole diagnosis.
