socialite - facebook login

Hi there guys, I am in trouble with socialite facebook login.

I set up my facebook app and integrated fb login on this first site:

http://test.spiaggiasrl.com/

and everything works fine.

Then, I set up a new facebook app and cloned the site on:

http://weplaya.it/test/

(of course I set up all the new parameters)

and here the system gives me this error:

(look at http://weplaya.it/test/login? code=AQAoTg2RlpIWn5pVUWlP8VRxNd6j0RQmXK89aXDLzvBO3mvZ3qjuXLQsKwIagrEXa3wLjpeNQg_2F-Sls6vyxrHCYmqzW0qX0CoREecy1d_5yi9lt5ReEN5CO2h9mDJTX1d3kcogtDUUNEDs20YvPcFIm8ZtKFSuSkkKo9nOaofCm7_NBjjxnrYR-GP0kuWhi3YRO8gZg9qPr605YS4P57h0Wo8Xy4JpF3L-aKSha8Z6EufMU_oL1WfTsbaCF74t4DjMCJe_tKLr4nKBSX8-3L-ljkoQ_pGd-7b8lpJ3QCK3LO0CPvQ18cr9ETYvnd32Hd8&state=a30499f1fbb6df2524d980506cc99d13bf31b902#=)

RequestException in RequestException.php line 51: Invalid state: before StateException in RequestFsm.php line 65: Invalid state: before

The two sites are on the same hosting platform...

Any ideas???...please help me, thank you in advance!!
