 * With this migration since Saturday, March 12th iframe apps on Facebook.com can
   no longer use preload FQL. Please note that preload FQL will continue to work
   for FBML apps and that the discontinued support of preload FQL for iframe apps
   does not impact FQL.
    Is there any turnaround to apply? Are you working to anew
   WPbook version to solve the problem? Many thanks in advance

 * You should update to 2.1, which I’ve just tagged as stable so it will show up
   in the next 30 minutes or so.
 * Make sure you review the notes I published in another thread in the forum – there
   are significant changes in 2.1 if you are coming from 2.0.x – if you were already
   on 2.1b1 or 2.1b2 you will have already done these.

 * Many thanks for your prompt answer. I installed the latest version. Ia replaced
   the APP Key with the APP ID. I clicked on the Chech Permissions link and got 
   beck the message “impossible to show the page” as the facebook were in maintenance
   or there was a programmin error. Could you help me?

 * Never seen the “impossible to show the page” error – had you already saved the
   changes you made to settings, before clicking on the check permissions link?

 * Yes I had saved the changes before clicking. The error code shown on Facebook
   page is HTTP 500.

 * [@olivieri](https://wordpress.org/support/users/olivieri/) – my guess is this
   means something is wrong/missing in the settings.
 * Just to be clear, go to <blog>/wp-admin/options-general.php?page=wpbook.php
 * And open the Stream/Wall Permission section.
 * The link marked “check permissions” should look something like this:
 * `http://apps.facebook.com/<app_name>/?is_permissions=true&wp_user=2`
 * Though the wp_user in your case might be different.
 * Is that the link where you are getting an error code 500?
 * What is the url of your facebook application?

 * Yes i was working in the setting page of wpbook.
    The check permissions link 
   is [http://apps.facebook.com/repsiamonoi/?is_permissions=true&wp_user=1](http://apps.facebook.com/repsiamonoi/?is_permissions=true&wp_user=1)
   that is the link where I get HTTP 500 error code. The url of my application is
   [http://www.facebook.com/developers/#!/developers/apps.php?app_id=191556547543768](http://www.facebook.com/developers/#!/developers/apps.php?app_id=191556547543768)

 * So that HTTP 500 error code is not coming from Facebook but from your blog, at
   this url: `http://www.legroma.osservatoriodeilaici.com/wpress_it_IT_292XXL/?cat
   =8&is_permissions=true&wp_user=1`
 * I assume that you have mapped:
    `http://www.legroma.osservatoriodeilaici.com/
   wpress_it_IT_292XXL/?cat=8`
 * As the website url in Facebook? You only want to include posts from certain categories
   or something?
 * The `&is_permissions=true&wp_user=1` is added by WPBook to let wpbook know it
   should be trying to present the permissions page.
 * Any chance you have access to the server logs to find out what error the server
   is throwing?

   and the Canvas url is [http://www.legroma.osservatoriodeilaici.com/wpress_it_IT_292XXL/?cat=8](http://www.legroma.osservatoriodeilaici.com/wpress_it_IT_292XXL/?cat=8)
   It follows the server error log I got after clicking the check permissions link.[

   the page link the post of the Canvas URL appear within Facebook without any share(
   or like) button or link to show the post in my blog.

    the more frequent error is as follows [Tue
   Mar 15 14:09:02 2011] [error] [client 66.249.68.110] Request exceeded the limit
   of 10 internal redirects due to probable configuration error. Use ‘LimitInternalRecursion’
   to increase the limit if necessary. Use ‘LogLevel debug’ to get a backtrace.

 * Do you have some .htaccess rewrite rules added for your blog?
 * This is a configuration error of some kind, often triggered by attempts to prevent
   blog hotlinking or reframing.
 * Can you try setting your Canvas URL without the category restriction? I know 
   I’ve never tested using just one category or any canvas URL which already includes
   a query string.
 * It would be helpful to know if that’s the issue.

 * This is the .htaccess file content i found in my blog (I hope it is the right
   one: # Use PHP5 Single php.ini as default
    AddHandler application/x-httpd-php5s.
   php
 * I tried to set the canvas url without category restriction but i am having the
   same error

 * This doesn’t look like the right .htaccess file, since it typically has some 
   WordPress stuff in it.
 * Are you using the default permalinks structure, rather than ‘pretty permalinks’?(?

 * This error is happening at the Apache level, not even the WordPress level – not
   sure how to even troubleshoot it.
 * Quick google search on the error suggests you should be able to turn on rewrite
   logging in apache’s main config and see what the looping request might be.

 * I changed my .htaccess as follows:
    # Use PHP5 Single php.ini as default AddHandler
   application/x-httpd-php5s .php
 * # BEGIN WordPress
 * # END WordPress
 * Nothing changed. I think I am using default permalink structure since i did nothing
   to change.
    I am not able to follow you regarding your suggestions on apache’s
   main configuration and the looping request …… since I am not a programmer. However
   if there is something I can do please let me have detalied instructions and I
   will try
