This article gives troubleshooting steps for problems with Messenger plug-ins.

If the Plug-in you're trying to install fails or isn't working, it could be because:

• The Plug-in may not be certified by Yahoo!. Yahoo! isn't able to support Plug-ins made by third parties that we haven't certified.
  • Note: The steps further below can still be used to troubleshoot third party plug-ins.  If the issue persists, check the plug-ins "Help" or "About" information to contact the developer for further assistance.
• The Plug-in may be pulling information from a source that is down or having problems at the moment.

Uninstalling and reinstalling the Plug-in that's causing the problem might solve the problem.

Here's how to uninstall and reinstall the Plug-in in Version 8.1:

1. Click the Plug-ins button with the green puzzle piece.
2. Click the My Plug-ins tab at the top of the screen. You should now see your installed Plug-ins.
3. If the Plug-in has a red Stop button to the right of it, click this Stop button now. (If the button says Start, do not click it.)
