 * Hi there!
 * First of all: thanks for this amazing plug-in, I’m really satisfied with the 
   way it works. However, since the most recent update, some of my albums don’t 
   show thumbnails any more. If you click the thumbnail, the image loads but the
   thumbnail itself is just a gray box. When I debug in Chrome, it says that the
   images could not be retrieved with the error code 403: Forbidden. My two most
   recent albums seem to work however, it’s for older albums that this does not 
   work.
    Here is an example of a non-working page: [http://chirodeketen.be/sympathisantenfeestje-2014/](http://chirodeketen.be/sympathisantenfeestje-2014/)
 * Kind regards

 * Yes, sometimes if you use Facebook links directly rather than importing them 
   to WordPress, the links appear to change. If you click the “sync” link it should
   correct the problem.

 * Hi Mike
 * Sorry for the late reply.
    This does not however seem to resolve the problem.
   When I press sync something flashes but nothing happens.

 * No worries. Are you using the latest version of the plugin (version 0.5) and 
   have you created a Facebook App and hooked it up to the plugin under the “Import”
   tab. These things are required now since Facebook deprecated the older version
   of the API I was utilizing. If it’s not that, let me know. There are a few things
   in the plugin I have to optimize which are on my list to do.
 * Thanks,
    Mike

 * Yes I have created such an app. I don’t know if this matters but in the developer‘
   area’ of Facebook it says ‘Not available to all users because your app is not
   live’ ([http://i.imgur.com/cY7dSOD.png](http://i.imgur.com/cY7dSOD.png)). Does
   this have anything to do with it?
 * Secondly, when I enter my app id under “Import” I get two things.
    1) Log in 
   with facebook and show albums. However, when I press “Log in” it gives me this
   error: [http://i.imgur.com/f8v3bPi.png](http://i.imgur.com/f8v3bPi.png)
 * 2) Find albums on a public page (which I believe is what I need to do). It gives
   me this error: [http://i.imgur.com/rzQeRKU.png](http://i.imgur.com/rzQeRKU.png)

 * Never mind, just found the fix 🙂 You have to make sure Web OAuth is enabled 
   in your app and add the URL from where you’re logging in. You migth want to add
   this to your plugin description/installation 😉

 * Yup! Sorry, instructions aren’t very clear (and has been an issue for others 
   as well). The 0.5 release I made was done in a rush because Facebook was deprecating
   the old API, so I didn’t put as much time into it as I wanted to. I’m in the 
   process of working on the new release that fixes a few issues others been having.
   I’ll work on the instructions as well to make them more clear. Thanks!
