 * [@penseelibre](https://wordpress.org/support/users/penseelibre/) It looks like
   some core WP-optimize files are missing.
 * Could you please try to upload the plugin files via FTP/SFTP instead?
 * It looks like updraftplus folder already exists inside wp-content/plugins folder,
   could you please try to upload the plugin files via FTP/SFTP instead?
 * To do this:
 * 1. Unzip the WP-Optimize ZIP on your local machine, using a zip utility such 
   as 7-zip.
    2. Access your WordPress installation via FTP or your host’s filemanager.
   3. Navigate to wp-content/plugins. Upload the WP-Optimize folder here. 4. Go 
   to the Plugins page on your WordPress dashboard. You should see WP-Optimize in
   the list of plugins.
 * Let us know if above steps helps to install the plugin?

 * Hello,
    I don’t understand what you are talking about. My version is paid, and
   I had to deactivate it from ftp by putting an -X on the extension name because
   wp informs me (and this has happened to me several times) that my site : “Here,
   WordPress found an error with one of your extensions, “WP-Optimize Premium – 
   Clean, Compress, Cache”..
 * and my host is putting my site under maintenance due to this error.
 * So how do I fix these problems?
