I had this exact problem on a Page Tab app and for the life of me couldn t work out what the problem was  It worked on my test page but as soon as I made it live it wouldn t work  I found in the end that I fixed the problem by putting the actual URL to the Page Tab  i e  http   www facebook com  lt  page name  gt  app  lt  app id  gt   into  Site URL  under  Website   This doesn t make any sense  But it worked  -

I just encountered this problem myself   I m developing an app internally  so my host is  localhost    It wasn t obvious how to set  localhost  up in the app configuration   If you want to develop locally  set up your app by following these steps    Go to the place where you manage your Facebook app   Specifically  you want to be in  Basic  under the  Settings  menu  Add  localhost  to  App Domain   Under  Select how your app integrates with Facebook   select  Website   and enter  http   localhost      Save and wait a couple of minutes for the information to propagate  although it worked right away for me

If you re the app developer  you may see a more specific error message  but generally that message means one of two things    Your server returned a HTTP error code  usually 5xx   You tried to send the user  after login  to a URL not allowed by your app configuration  though as an Admin of the app  you should see a more specific error message and Facebook error code in this case

Came here with a similar problem and  yes  my Sandbox was enabled  I disabled it and  voila  the login problem went away  I must warn that this problem does not affect developers and website administrators as Facebook allows those users to see the app  For this reason  I couldn t even believe that users complained about not being able to login  as I was able to login with no problems at all

For me the problem was that the Facebook users I was using to test the app did not have its email address confirmed by Facebook   My client had set up 2 fake accounts on Facebook and told me that they were not working  But he forgot to confirm the email addresses of those accounts  the emails Facebook sent went to his spam folder and he didn t notice    Took me hours to find this  so I hope it helps somebody   Cheers

The reason in my case was completely different  I was trying to open a Feed dialog automatically after page load  And 9 times of 10 it displayed this error  First  I added show error  true parameter as suggested by  Peter Roome  but it didn t help  displaying 104  Invalid signature  not descriptive at all   Then I figured out the reason  The code was in   document  ready jQuery function  And it seems that some facebook stuff had not yet been loaded at the point the code was to be executed  I moved the code to   window  load block  which is executed after all page content is loaded   and the problem has been solved

For me the issue was that the url of the app didn t completely match the url I was running it on  i e different directories  same domain

User · Answer

This was happening to me also but all the api keys  secrets and stuff were correct  What I found is that my app was running in sandbox mode  Go to your app settings in https   developers facebook com  click the advanced settings tab and check to see if your app is in sandbox mode  If it is disable it and try again  Let us know if it works

User · Answer

Another possible mistake  if you directly copied the code from Facebook SDK example then you may get the same error despite of having everything correct  http   developers facebook com docs reference php   This is because in their example they have used backquotes instead of single quotes for the key of the array  The correct code is as follows   require once  facebook php      config   array     config  appId      YOUR APP ID    config  secret      YOUR APP SECRET    config  fileUpload     false     optional   facebook   new Facebook  config

When working with Dialogues  Facebook provide a  show error  attribute that defaults to no but can be set to true in a Development environment and is really helpful for debugging purposes   show error - If this is set to true  the error code and error description will be displayed in the event of an error   Instructions of it s use can be found in the Facebook Docs  I d been debugging  quot An Error occurred  Please try later  quot  dialogue before i found this attribute in the docs  Once i started using it  i could see the following message too   API Error Code  191 API Error Description  The specified URL is not owned by the application Error Message  redirect uri is not owned by the application

I had the same problem after changing the domain of my site  Altough I properly changed the request uri parameter and updated my app settings with the new domain  the error kept showing up   Then I realized that the ID and the SECRET ID of my Facebook APP had automatically changed with no warning   The whole thing started working again using the new ID

User · Answer

The issue resolved after I updated the  appID  and  secret  and then pushed the change back to heroku  i e  -  git push heroku master    The key is not to forget to push the changes back to heroku master  Very easy to overlook if you re use to testing on localhost   Hope this helps

Also had a problem with wrong redirect link  I had a link starting with  https   apps facebook com myapplication      but after authorization the redirection would bring me to  apps facebook com Myapplication  and consequently I would get a message described above  Error occured   Try back later   since  apps facebook com     means  http   apps facebook com Myapp  and not  HTTPS   apps facebook com        The solution  went to my application settings in facebook developers section  Clicked  Edit   In the left-side Menu selected  Permissions   by default the Menu is set to Basic  and in the newly opened set of setting changed my  Auth Token Parameter  from  Query string  to  URL Fragment    It worked  After authorization is finished the users are taken to  https   apps facebook com myapp

In my case  there was an age issue with the account being used with the app    If the FB app has alcoholic content then FB users who are younger than about 21 will throw an error when trying to authorize with it

I had this error because I was using redirect url as a parameter instead of redirect uri   The Server-Side Authentication doc page says to use redirect url   https   www facebook com dialog oauth      client id YOUR APP ID     amp redirect url YOUR REDIRECT URI     amp scope COMMA SEPARATED LIST OF PERMISSION NAMES     amp state SOME ARBITRARY BUT UNIQUE STRING   But this is incorrect   The OAuth Dialog doc says to use redirect uri instead  which works  so I m assuming that you can only use one and not the other   https   www facebook com dialog oauth       client id YOUR APP ID      amp redirect uri YOUR REDIRECT URL      amp state YOUR STATE VALUE      amp scope COMMA SEPARATED LIST OF PERMISSION NAMES

I had tried all the answers mentioned here  But it didn t work  I had to delete and create again  I am guessing it was due to new the  Authenticated Referral   If you have added Open Graph objects which are not approved  it might give you an error

User · Answer

There is no possibility to solve this type of error  So Its better to use your custom dialog same like shown in facebook and post message again  amp  again without login  Even though you remove your app from facebook  you can ask for login and post message successfully

According to OAUTH Dialog documentation    redirect uri  The URL to redirect to after the user clicks a button in the dialog  The URL you specify must be a URL of with the same Base Domain as specified in your app s settings  a Canvas URL of the form https   apps facebook com YOUR APP NAMESPACE       I am constructing oauth links dynamically to ask a user for additional permissions if needed and I realized  that even if you are redirecting to https   apps facebook com YOUR APP NAMESPACE you have to have  the App Domain and Website settings set in your application administration  I set domain to facebook com and Website to facebooks root url   Now my oauth dialog link works fine - even in sandbox mode
