    Hard to say – depends on your settings being accurate.

    What is the url of your blog outside Facebook?

    What do you have set in Facebook settings as your application’s canvas URL?

    It looks, from the page you sent, like you are trying to load:

    as your Facebook tab.

    Does your wordpress install live at ?

    Based on the above, I assume your app’s canvas page is:

    Which tries to load your blog in an iframe but seems to return:

    <script src="" type="text/javascript"></script>
    	<script type="text/javascript">
    	var load_cmc = function(){linktracker_init(36215287,0,2);};
    	if ( typeof addLoadEvent != 'undefined' ) addLoadEvent(load_cmc);
    	else load_cmc();

    Some kind of stats tracker js that is being returned instead of your blog when called inside the iframe?

    Facebook basically tries to load your blog in an iframe – something on your blog is preventing that from happening.

    Any entries in the PHP error log for the blog in question?

    Hi there.

    it seems, that the wpbook plugin crashes the fb integration. We have two apps at fb, one using wbbook, another is just displaying the imprint page on the fb page.

    as soon as the wpbook plugin is activated, the imprint integration does not work any longer. When i deactivate the wpbook the imprint integration works fine.

    Would it help, if I give you admin access to the wp installation so you can chek ? If so, please send me an email.

    kindest regards and thx in advance for your help.

    @netmorix Not exactly sure what you mean by “another is just displaying the imprint page on the fb page” – is that another plugin, or another Facebook application mapped to the domain?

    I think there are two potential issues I know of (there may be others too!):

    1. If you have multiple plugins in WordPress which offer Facebook related functionality, and they expect/include different versions of the Facebook library, you can get collisions. WPBook does check to see if the Facebook class exists before (re)declaring it, but if the versions mismatch this can be a problem – whoever includes the Facebook API first “wins” and the other plugin loses.

    2. If you have multiple applications in Facebook mapped to the same domain you may have issues.

    Is the “imprint integration” a plugin?

    displaying the imprint is just another Facebook App mapped to the domain with a parameter call.

    Sorry, but it still isn’t clear to me what you mean by “displaying the imprint page on the fb page.”

    I don’t know that having two different Facebook Applications mapped to the same domain is supported by Facebook. Do both applications have exactly the same URL as base domain, or are they different?

    By “with a parameter call” you mean that the WPBook application is mapped to but the other is mapped to

    When you try to load your WPBook canvas page –

    Do you get any error messages in your PHP error log?

    Without some error messages I don’t know how I can help.

    But my guess is that there error is on the WordPress side and is related to these two FB applications.

    What code, in WordPress, causes the “imprint integration” to be enabled or disabled? When the WPBook plugin is disabled, and the “imprint integration” is working, how do you know it is working? Does something show on the fb page, or does something show on the wordpress blog outside FB?
