 * Hello [@brutforce21](https://wordpress.org/support/users/brutforce21/)
 * I am sorry about the issue you are experiencing and I am happy to assist you 
   with this.
    The PHP warning is suggesting the invalid regex in the Performance
   >Page Cache>Advanced section of the plugin. Have you added andy regex to exclude
   any pages from being cached or disabling caching on the pages that contain cookies?
   Also, if you are a paid customer, you can drop us a note via the plugin in Perofmrnace
   >Support. Thanks!

 * I have added previously but already removed.
 * Currently:
 * Rejected cookies:
    wptouch_switch_toggle
 * Never cache the following pages:
    wp-.*\.php index\.php
 * Everything else is default or empty.
