    plugins - White blank screen while adding or editing pages in wordpress

    matteradmin11PV0评论

    I am not able to add or edit pages in wordpresss . When i go to the page edit option in wordpress a complete white blank screen is showing with the error message –

    (Warning: call_user_func_array() expects parameter 1 to be a valid callback, function ‘wp_cache_set_posts_last_changed’ not found or invalid function name in /home/accounts/public_html/wp-includes/class-wp-hook.php on line 288)

    All the things was working fine some days back . I have also tried to deactivate all the plugin to make sure it will not be due to any plugins but even after deactivating the plugins error is still showing.

    I have already done lots of R & D to solve this issue but nothing works..
