 * Hi,
    just updated the plugin to the latest Version 1.0.8 this morning and then
   everything crashed. I managed to get everything up again, but these error messages
   keep appearing:
 * Warning: session_start(): Cannot send session cache limiter – headers already
   sent (output started at…./wp-content/plugins/gwolle-gb/gwolle-gb.php:108) in …./
   wp-content/plugins/nav2me/nav2me.php on line 30
 * Can someone please help? Need to get the Guestbook urgently working for the customer.
   Thanks

 * Aye. Same error message on all actions. Had to deactivate plugin for site to 
   work properly.

 * Seems to clash with the Nav2me Plugin which I had installed. Deactivating Nav2me
   solves the error. Nevertheless, I’d still like to continue using both Plugins,
   so if there’s a quick fix, That’ll be great. Thanks

 * Same issue. I don’t have Nav2me installed but when updating any pages, I get 
   the above error message. When I view the pages separately, I see the changes 
   have been made, but it’s annoying nonetheless.

 * Tried installing other route planning plugins (about 3), all clashed with the
   guest book plugin with the same errors.

 * Hi, Version 1.0.9 has the fix.
 * It was because of a slight error, a PHP closing tag with some whitespace, which
   generated output, making sure that no cookies or headers could be set.
 * If you have a broken login function, you can log in to FTP / SFTP, rename or 
   remove /wp-content/plugins/gwolle-gb.
    After logging in you can install the plugin
   again.
 * Alternatively you can download the 1.0.9-zip, unpack it, and upload these files
   to the correct location.
 * Again, sorry about this.
