When trying to edit a page, an error message appears, "You can't edit this page now because (username) <email address> is currently editing it. Please contact <email address> for assistance."


The possible reasons for this issue:

  • In order to prevent users from overwriting pages that are being edited, Contribute uses the Check In/Check Out feature. To make this feature work, Contribute uploads a lock file (LCK) to the server when a user edits a page. If another user attempts to edit that page, they will get that message. The said file would be removed once the user editing the page publishes or cancels the draft.
  • If you have verified that no one else is editing the page, another possible cause of this message is when the Lock file (LCK) associated with the page is left in the server. This commonly occurs when Contribute crashes while a user is editing a page.


Check if someone else is editing the page. Contact the Site Administrator or the user indicated in the message and ask for assistance. If someone is editing the page, make sure that they published it or cancel the draft.

After verifying that no one else is editing the page, the last resort is to remove the lock file from the server.

Using Contribute 4 and 3.1

Administrators may remove the lock file by clicking a link under the address window:

Note: Contribute 3.0 users may download and install the Contribute 3.1 updater.

Using earlier versions of Contribute

Contribute 3.0 and earlier versions do not have the ability to remove the lock files. Users may have to use another application to connect to your server and remove it:

Using Dreamweaver to rebuild the Contribute connection

  1. Delete the _mm folder from the server where the problems are.
  2. Rebuild the Contribute connection from Dreamweaver.

Using Dreamweaver to check out and remove the lock file

  1. Open the site files and go to Remote View.
  2. Select the file that users cannot edit in Contribute.
  3. Choose Site > Undo Check Out.

Using other applications to manually remove the Lock file from the server

If you are connecting through FTP, connect to your server with an FTP client. Several FTP clients are available for free or as shareware. WS_FTP is a common FTP client for Windows. Locate and delete the lock file.

If connecting through Local/Network, connect to the server with a Network Browser. Locate and delete the lock file.
