[Plugin: Facebook album] – Application request limit reached

Hello,

I would like to display on my blog some photo gallery extracted from facebook public pages.
I have found many plugins like: “facebook albums”, “facebook page photo gallery”, “srizon” but none seems to work.
I spent some time trying to debug (at my little level) “facebook album”, and I’ve found out that I actually get an error message from facebook(?): Application request limit reached.

I’ve understood it’s a security from FB for avoiding floods of requests, but that’s not my case at all. My blog is known only to me, with 3 example articles trying to display photo galleries.
I’ve tried from my PC at home, from an other PC at work, same result.
I have disabled all other plugins (in particular cache plugins), and I have switched back to a standard theme (twenty twelve) in case it would help, but it does not.

Googling “Application request limit reached” brings a lot of noise but no answers.
I’m starting to think about a limitation from the server where my blog is hosted, but the server belongs to one leading host company in France, so that would be weird.

I must be missing something…any hints from the community?
Thanks
