 * Hi all,
 * I’m getting the white screen of death every time I try to access wordpress control
   panel. The problem gets kind of fixed when I rename my custom theme folder and
   then rename it back to its original name via ftp, since I get access to wordpress
   by doing so, but then everytime I click on save changes in entries/pages, I get
   the white screen again, eventhough changes are saved. Also, when I log out and
   then log in, the problem appears again and I have to do the renaming thing to
   fix it.
 * Things I have done so far:
 * wp-config and wp-functions files have ?> closed and no blank space on top or 
   at the end.
 * I have renamed the plugin folder to plugins_old so plugins don’t work. White 
   screen still appearing.
 * debugging says (I translate it since I have it in spanish):
 * Error calling main_sidebar, undefined ID for main_sidebar -> That, I already 
   fixed it by putting ‘id’ => ‘sidebar-1’ in the array inside functions.php
 * Then there is this one:
 * PHP Notice: Undefined index: no_post_titles in …/wordpress/wp-content/plugins/
   list-category-posts/include/lcp-catlistdisplayer.php on line 234 [06-May-2015
   07:13:38 UTC] PHP Notice: Undefined index: no_post_titles in
 * I copy and paste that line of code:
 *     ```
       if ( empty($this->params['no_post_titles']) || !empty($this->params['no_post_titles']) && $this->params['no_post_titles'] !== 'yes' ) {
         $lcp_display_output .= $this->get_post_title($single);
       }
       ```
   
 * Anyway, I have disabled the list category post plugin, white screen still showing
   up.
 * Any help please?
