I need your help to resolve 1 Issue in Wordpress admin page. I'm using WP 3.7.1 and twentytwelve template. I have some posts and pages. Currently, when I click Filter or Apply button in Post/Page list, it always shows the error "Invalid Post Type" and the URL looks like this .


I tried to active another template and it works fine!

Please help me to understand and fix this issue!!! Thank you!!

    Try disabling all plugins, reactivating the theme, and trying again. See if it works as expected. My guess is a plugin/theme conflict. – Michael Ecklund Dec 10 '13 at 17:02
