 * Received the following error message when accessing mywordpressblog.com/wp-admin:
   
   Warning: Cannot modify header information – headers already sent by (output started
   at /home/content/77/6690377/html/wp-content/plugins/islidex/islidex.php:1170)
   in /home/content/77/6690377/html/wp-includes/pluggable.php on line 890
 * I understand that most likely the issue is that when I installed the islidex 
   plugin that the wp-config php code was altered by adding a space somewhere.
    
   However, how do I edit my blog php code without being able to log in to my wordpress
   admin panel via mywordpressblog.com/wp-admin? Is there a way for me to delete
   the plugin all together without loggin in to my admin panel?
 * Thanks

 * No the most likely cause is from the plugin.
 * Yes you can FTP to your site and rename the islidex plugin directory to something
   else.
