WE tried to unpublish a page from the CME in Tridion 2013 & it was marked successful. However, the unpublish was not successful because the page is still in the Broker DB. How do we get rid of the page? How do we diagnose issues like this? We looked through the Deployer logs & did not see any error related to that page.

**UPDATE**

For the record, I followed the steps listed in [this](http://tridion.kb.sdl.com/#tab:homeTab:crumb:7:artId:5315) kb article. Make sure to hit the appropriate HTTPUpload.aspx page so that the package is picked up. That worked.

Also, convince yourself the Structure Group the Page is in is marked 'Publishable'.
If this is not the case a Publish or Unpublish action will be 'Success' in the Queue, but nothing really happens.
This is one of those annoying issues where the CM and the CD DBs are out of sync for an item. I believe this was addressed sometime in the 2011 SP1 release, but it looks like you're still experiencing it. 

There are two ways I've dealt with this:

1. Submit a support ticket, they'll give you a SQL script to run on your CM DB to force set the page to "unpublished". You can then republish it and all is dandy.
2. Force set the page to unpublished via the CM DB yourself. Note: this risks voiding the warranty if you mess anything up. I do this in my own sandbox VM all the time, but there is no risk there. Consider yourself warned. Here is how: update the STATE column for your Page's (REFERENCE\_ID = page ID) record to 0. Back in 2011 there was another table with this status that needed updating, but I don't see any other "STATE" columns in the DB in 2013.
