# Problems with the PRO version

 * Hi,
 * I have a bug to report. Once I uploaded the files and activated the extension
   on WordPress with a “pro” licence, I can’t see the calendar to display and program
   the events, nor the places to be reserved. Moreover, the schemes show me numbers
   that I can’t work with instead of the “squares” for the places. Is it due to 
   installing Book a place (free) and then Book a place (pro) ? I also tried to 
   clear the database before reinstalling only the pro, and same problems…
 * All seems to work fine with the free version, but I can’t integrate the payment
   system to it (that’s why we bought the PRO).
 * Thanks for your reply.

 * Hi,
    Please try to remove the Basic version. And then install the Pro one. I 
   think everything should be fine.
 * If nothing happened, please contact me using the email address in the help document.
   We will need your site URL and access to wp-admin etc.

 * Hello, Djusha
 * You do something wrong.
    I’m sure that we don’t have such class Book_A_PlacePro.
   And you get the same message from the system.
 * Please don’t rename directories, don’t change anything in files and you will 
   be able to install the plugin correctly.
 * Please let me know, when you try.
 * Regards,
    ArtkanMedia
