 * I installed your plug in on my client’s site [http://www.styleconfidante.com.au](http://www.styleconfidante.com.au)
 * Since installing and activating, I have been locked out of the front end site,
   the plug has disappeared from the back end plugins folder and I receive these
   errors on the home page:
 * Notice: Constant WP_DEBUG already defined in /home/stylec/public_html/wp-content/
   plugins/the-logo-slider/the-logo-slider.php on line 11
 * Warning: Cannot modify header information – headers already sent by (output started
   at /home/stylec/public_html/wp-content/plugins/the-logo-slider/the-logo-slider.
   php:11) in /home/stylec/public_html/wp-includes/pluggable.php on line 1228
 * Urgent help would be greatly appreciated. Thank you
