 * Hello,
 * I installed this Plugin but got a warning once I activated it:
 * Warning: session_start() [function.session-start]: Cannot send session cache 
   limiter – headers already sent (output started at /home6/thechess/public_html/
   wp-content/plugins/embed-chessboard/embedchessboard.php:590) in /home6/thechess/
   public_html/wp-content/plugins/faq-builder/config.php on line 2
 * Could you please help me fixing the warning?
 * Thanks.

 * Hello, I’m the author of Embed Chessboard.
 * I dont have much experience with wordpress plugins, so be patient with me.
 * First question is: does the plugin actually work (regardless of the warning message)?
   I’ll check, but I might have reduce the amount of warnings displayed by [my test site](http://pgn4web-test-wp.casaschi.net/).
 * Second question: how did you install the plugin? I just deleted and reinstalled
   the plugin from [my test site](http://pgn4web-test-wp.casaschi.net/), using the
   tools in the “manage
    plugins” section of the worpress admin section of my site(
   so no manual download and ftp, everything done from the admin panel). If you 
   did something different (like manual download and ftp) you might want to try 
   this.
 * Last suggestion (for now): the “wordpress” part of the plugin has been copied
   very much from another plugin called “Embed Iframe”. First thing to understand
   what’s going on and what’s causing the error/conflict would be to follow the 
   instruction of the wordpress.org section of [this page](http://code.google.com/p/pgn4web/wiki/User_Notes)
   to use “Emebd Iframe” and then use it to display chess games.
    I would be interested
   to know if “Embed Iframe” works on your site or if it shows the same warning (
   good thing is that if the Embed Iframe method works you could actually ditch 
   Embed Chessboard and add your chess games using Embed Iframe, but I should not
   advertise this too much).
 * Good luck and thanks for trying the Embed Chessboard plugin!

 * Thanks for the quick reply>
 * 1) I do not know, I did not check, hours ago, I could not log into my blog to
   check if the plugin works or not, as I mentioned in another post, I had to delete
   the plugin files using FTP. My site is OK now, but I did not check the plugin.
   
   2) I used the manual download and ftp method, I just tried the method you mentioned,
   installation was fine until the final step, once I activated the plugin, the 
   same warning resulted. So both of the methods do not work. 3) I installed “Embed
   Ifame”, no warning, nor error, but I can not show an external website. For example,
   I used [iframe [http://www.google.com](http://www.google.com) 400 500], my own
   website was in the frame, instead of the google site. So “Embed Iframe” does 
   not work on my site using WordPress 2.9.1.
 * Thanks.

 * Thanks for the feedback.
 * I was able to replicate the warning on a fresh install of wordpress 2.9.1
 * The current version 1.02 of the Embed Chessboard plugin does not get the warning.
   
   Please try version 1.02 and let me know.
 * Thanks.
