 * Hello: Your plugin has crashed my site. I couldn’t get into my dashboard without
   assistance from my hosting provider. When I tried to delete the plugin, it refused
   to delete. The error message(s) are below. Please help. I’ve been using your 
   plugin for years, and I changed nothing on my site when the plugin suddenly started
   malfunctioning. I would like to use your plugin again, but it appears to be corrupted.
   I am open to suggestions. Note: I am not a web developer, and I do not understand
   code. Thank you.
 * Messages resulting from the crash:

 * Can you please try to upload the plugins files via FTP/SFTP and check if it helps
   to fix the issue?
 * 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.
 * Thanks,
    Harshad
