 * after upgrading to version 5.3 earlier today I get the following messages when
   trying to log-in to the wp-admin page or access the home page of the website (
   I have changed the site name below). Any help would be good.

 * You obscured the site’s URL so I can’t tell for sure but there’s a plugin called
   WP File Manager or something like that. Disable that plugin and your problem 
   will probably go away.
 * If not come back and let us know.
 * If you need that plugin then figure out where it came from and contact the source
   for help with it.

 * Simple delete `wp file manager` from plugins by panel or cpanel/ftp. (As said
   by jnashawkins)
 * **This error is due to incompatibility with outdated plugins. So after bugfix
   update you can reinstall it.** for now there is no update for this plugin.

 * For pro version click Contact us for Support Only Pro Version Users.

   they’ll probably ask you to install again.

 * Many thanks for the advice. I have deactivated the plugin by changing its name
   and I can now login via the admin page. I didn’t develop the site so I am not
   sure why it is there, it seems to be a FTP type replacement. I have raised a 
   support ticket with them so I will see if they respond.
