 * Hello, I am using this plugin with the latest version of WordPress on my site:
   ufvsoca.ca. My Booked Scheduler site is: [https://spacebookings.ufvsoca.ca](https://spacebookings.ufvsoca.ca)
 * I tried to use the short code to add a schedule to a WordPress Page. However 
   I am getting this error: PHP Notice: ob_end_flush(): Failed to send buffer of
   zlib output compression (1) in /home/socatech/public_html/wp/wp-includes/functions.
   php on line 5471
 * I have tried deactivating all other plugins and tried another theme but I still
   get the error. Wondering if this is an issue with the Booked Scheduler plugin?
