Views not found on disabling Page Title module I've  Views 7.x-3.7 and Page Title 7.x-2.7 installed. Since many months I'm using Meta tags and Page Title module but now I want to remove Page Title module as I don't need it since Metatag module provides equivalent functionality.

But on disabling Page Title module I'm getting page not found(404) for the Views Page display URL. Also when I go to edit that display in the View from Structure->Views I get the following screen:


  


When I go to view the Page url of the View Display I get this :


  


There is no information in the dblog except for this when I access the View Page url:


  


What should I check to start debugging this?
The page_titles module sets a lot of variables. I don't know if that would cause an issue like you are seeing, but it's best to remove these variables. Disabling the module will not remove them, but uninstalling it will. With page_title disabled, go to admin/modules/uninstall, select the module, and click uninstall. This will unset all variables that were set by the module.
