 * [@shapeschicken](https://wordpress.org/support/users/shapeschicken/) Thanks for
   your reply and confirming that Yoast SEO and WordPress are up to date.
 * The error you are receiving looks like it may have been caused due to an incomplete
   or faulty installation of the plugin, or that during an update of the plugin 
   something went wrong and caused some of it’s files to become incomplete or damaged.
 * To resolve this, can you please try performing a manual reinstallation of the
   plugin and see whether that corrects the issue? We have instructions on how to
   reinstall the plugin at the following link: [https://yoast.com/help/how-can-i-update-my-free-plugin/#remove](https://yoast.com/help/how-can-i-update-my-free-plugin/#remove).

 * Hey Devnihil
 * Thanks for your response and sorry i didnt get back earlier, few other fires 
   to fight and this issue resolves itself after a restart…
 * However, it happens once a week which is painful.
 * Can i confirm that if i do the steps with Deleting the plugin and then reinstalling
   it, will i still keep all my settings, including my meta data etc?
 * thank you
