 * Hi [@vanmanuel83](https://wordpress.org/support/users/vanmanuel83/),
 * A 500 Server error is usually a result of file corruption.
 * I suggest a manual reinstall. These instructions will preserve your current events:
 * – Perform a complete back up of your database before proceeding further
    – Delete
   the file uninstall.php from the plugin directory that is currently on the server(
   found under /wp-content/plugins/all-in-one-event-calendar). Deleting this file
   ensures that when you uninstall the current version of the plugin, your event
   data and calendar settings will be preserved when you delete the plugin (don’t
   skip this step – it’s important!) – Deactivate the All-in-One Event Calendar 
   using your WordPress Dashboard. – Delete the All-in-One Event Calendar using 
   your WordPress Dashboard. – Database -> wp_options, click option_name to sort
   and delete everything with ai1ec_, this will delete plugin settings but events
   will remain in the database. – Now install the latest version.
