'URL No Longer Exists' Error when trying to log in to take challenge
This has worked fine for me in the past but today I'm working through Data Security modules and when I click 'Login to Take Chalenges' I get a pop up 'Login with Salesforce Account' button. When I click that I get 'URL No Longer Exists'. Anyone else getting same?
Maybe just logging out and in again on the Trailhead page (as opposed to the popup) would work too as others suggest above.
Description
Including visualforce pages in page layouts causes the page to not load and receives error: URL No Longer Exist. The URL that the error refers to is the servlet/servlet.integration trying to load the visualforce page.
Resolution
Staring with Winter 13 release salesforce added a new feature in Setup -> Security Controls -> Session Setting ->
Enable clickjack protection for non-setup customer Visualforce pages.
Enabling this option will cause this error. To correct the situation simply disable this option.
Note: There may be other reasons for this error and this solution might not fix all those.
I have spent the last two days on a "URL does not exist" error in Campaigns related to an installed package (or so I thought). Salesforce Tier 3 support sent me to the package developer, and the package developer sent me back to Salesforce. Nobody was able to identify what was causing the issue, until I found this thread and realized we had "Clickjack protection" enabled, so I disabled it and everything works great now.
Thank you for saving me future wasted time and helping resolve my issue via this old thread!!
