Field type {field name} is not installed properly. Go to the list settings page to delete this field.

According to most of the documentation out there, the only possible way to delete this column is with a database query. obviously that is out of the question. The next best solution is to contact Microsoft. Can SharePoint Stackexchange do any better?


My points :

  • Cannot delete via the browser, as the page doesn't load with the above error
  • Cannot delete with powershell, as iterating the SPWeb.Fields property gives the same error
  • I'm currently looking into recreating a list with a reference to it
  • If you can, simply re-create the list.. Apr 9, 2014 at 7:37
  • I can't, I would have to hack it together by creating the list elsewhere, doing an export-spweb on the list, and manually editing the guids to point to the column, and for the column to point to the exported list

  • Actually that wouldnt work either, as this is a custom built "Type" - i.e. not a text field, date field, managed metadata field, lookup field, etc... i need to reactivte the feature that provided the type

I wouldn't touch the database. The SharePoint DB is very complex and you can break everything running queries on it.

If designer doesn't work for you, use PowerShell:

$webUrl = "http://theUrlOfYourCollection"
$columnName ="My column to delete"
$web = get-spweb $webUrl
$field = $web.Fields[$columnName]
$shadowField = $web.Fields[$field.TextField] # optional, only if the column has metadata
$shadowField.Delete() # optional, only if the column has metadata
write-host "fields deleted" -foregroundcolor green
  • See point number 2 - In this case I could not iterate over the SPWeb.Fields enumeration

If you cannot remove it by SharePoint UI, powershell, SPDesigner, SharePoint Manager remove it from the sql database. See here a tutorial how to remove/delete corrupted SharePoint column.


I dont see this error yet but I Think that sharepoint manager can solve this and delete site column! (Or sharepoint Designer) test them before delete list!

Sharepoint Manager

Open your site in SharePoint Designer. In the navigation panel select "Site Columns" and then find your site column in the list and delete.


Check this link I solved by problem following the steps using both SharePoint Manager and SharePoint Designer.
