 * The 500 Internal Server error could be caused by a few things. If you can’t get
   to your settings I recommend you update your WordPress to the latest version,
   and also be sure your host is using PHP version 5.6 or newer. Then reinstall 
   the plugin as follows:
 * – 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.

 * Hi, as I wrote this was a brand new worpress download and installation, no other
   plugins, all-in-one-event-calendar new installation and we had this problem.
   
   We changed to another working plugin. But thanks for your answer.
