  • After upgrade from 1.9.3 to last version of NGG. I canĀ“t remove ou set post thumbnail.

    Error was:
    POST *website*/wp-admin/admin-ajax.php load-scripts.php:4 load-scripts.php:4
    f.extend.ajax load-scripts.php:4
    f.each.f.(anonymous function) load-scripts.php:4
    WPSetAsThumbnail load-scripts.php:6

    After install a fresh install of WP and install only last NGG the problem remains.

    Solution: Back to 1.9.3 version e clean cookies.

    The last version sets some information in wp-settings-{userid} cookie. When I delete this cookie the problem goes.

    More information on last post on:

    NGG does not remove all settings from WP Database after uninstall plugin. See {prefix}_usermeta table and search for wp-settings key.
