Connection fails, .htaccess?

I have tried to disable absolutely all the modules except for fb oauth to check whether it was a module compatibility issue, and it still does not work = not a module compatibility issue...

Thanks for you quick answer. I followed meticulously point 1 to 7 of the “installation” section of the readme.

Perhaps I should add more details. The module seems to perform just fine in the beginning. Once I click on the FConnect button, I am redirected to facebook website, asked to login and grant access to precisely that information which I asked for when configuring the module.

(Also, when I misconfigure the facebook app, for instance by entering the wrong site domain, I am blocked much further in the process.)

The problem occurs when I am sent back from facebook to my website. Then instead of being connected, I receive the error message I mentioned.

I check drupal status report and pointed out two elements which might have something to do with this issue:

• PHP 5.3.25
  The phpinfo() function has been disabled for security reasons. To see your server's phpinfo() information, change your PHP settings or contact your server administrator. For more information, Enabling and disabling phpinfo() handbook page.
• Upload progress Not enabled
  Your server is capable of displaying file upload progress, but does not have the required libraries. It is recommended to install the PECL uploadprogress library (preferred) or to install APC.

Any thoughts?

PS : the error message mentions "Details about this error have already been recorded to the error log." I would love to be able to provide you more information about the error but I do not know how to acces the error log the error log from my server provider is either empty or inexistent... sorry

So there are two kinds of logs somehow related to the module. The first look like it might be related to the fb module rather. But I keep getting it although I disable every component of the fb module ( as I could not make if with fboauth, I gave a try to fb which turned out to be much more of a mess. But then I disabled and uninstalled it fearing that having both modules on my drupal might trigger incompatibilities)

The second is more neatly a fboauth issue:

Does not look much informative to me, but hope it can give you a clue...

It did not work unfortunately :(. Similar log error (the anonymous factor comes from the fact that I tried to connect from a different browser than the one in which I was logged in as an admin of my drupal) :

Here is a screenshot of my advanced facebook app settings, is there anything I should change?

PS : I am also allowed to set "Auth token parameter" to either "Query String" or "URI Fragment", does it matter?

Sorry to throw information at you, but I guess it is the best way to get to a solution : I also noticed that my app is mentionned as "Your app detail page has not yet been submitted for review." Does it matter for my problem?

I finally ran the debugging tool of facebook app with respect to my web site, and got the following warnings:

Open Graph Warnings That Should Be FixedInferred Property : The 'og:url' property should be explicitly provided, even if a value can be inferred from other tags.

yes query string is the default setting.

For the record, I should add that I have made sure that my hosting provider allowed for http requests.

Anyways, thanks a lot for your valuable support, I hope I can ultimately figure it out. I will post my solution here if I happen to find one.

improvement : changed guess for suggest
