An issue I’ve come across a few times when adding an Add This button to any .net application is that the following error message is thrown:
The string 'fb:like:layout' contains too many device filters. There can be only one.
There’s something about the Highlander with that one, and it’s a bit irritating to say the least, but the fix is a simple one.
<div class="addMe"> <!-- AddThis Button BEGIN --> <div class="addthis_toolbox"> <a class="addthis_button_facebook_like"></a> <a class="addthis_button_tweet"></a> <a class="addthis_counter addthis_pill_style"></a> </div> </div>
