I am getting this error in my wordpress website map_meta_cap was called incorrectly. The post type wpautoterms_page is not registered, so it may not be reliable to check the capability "edit_post" against a post of that type. Please see Debugging in WordPress for more information. (This message was added in version 4.4.0.) in /home/myusername/public_html/wp-includes/[login to view URL] on line 4773
All my installed plugins are missing also i am not able to install the new one.
