 * Hi I am getting the following
 * WARNING for Booking System! Not all PHP files needed to run the plugin are on
   the server, in folder wp-content/plugins/dopbsp. If you are installing or updating
   the plugin using FTP, please allow all files to upload, or try to upload them
   again. If you think all files are on the server and this message still exist,
   please contact us on our Support.
 * Please let me know what I should do? I have already de-activated & re-activated
   the plugin, but this has not changed anything.
 * Many thanks
