App name showing incorrectly on the ticker

We have an old name for the app and we want the app to show the correct name on the ticker but we have not been able to do it (it is still showing the old name). We updated the title of the url canvas and submitted it on the debugger and interestingly enough, the title is taken correctly on the https address (it is shown o开发者_StackOverflow社区n the debugger page but not in the ticker) but not on the http url. Actually it says for the http that the app has problems with the meta tags. Any idea on how to fix this problem? Thanks a Lot, Gilmer

Go to http://developers.facebook.com/tools/debug

Enter your url in that and try to generate all the information. If that is not showing any errors in that, then scroll down at the end of the page. You will find block named as "URLs"

Click on the first link named as: "Graph API:".

This will solve your issue.

In future, if you are going to change any content from your page, then don't forget to do the same process once again.

Thanks!
