Strange fb sdk behavior - facebook

On the PHP script I placed Facebook login button with FB SDK. Several days ago, I found that sometime login display is shifted down, and links on the page are not clickable. Very strange, it is not always but sometime appears in all browsers.
How to fix this problem?

Facebook app in Page Tab not visible to not logged in users (content not available)

I tried to create my first facebook app. It is a simple countdown to a specific date (does not require user to log in, or anything). It is added as a Page Tab on my page. The problem is, that while the page tab is visible to everyone, the app itself is visible only to logged in users. When I log out, I get "content is not available" message after clicking on the tab.
When I go to "Canvas page"https://apps.facebook.com/xxx, I can view it even if I am not logged in.
I have no restrictions in the app settings, and the app is hosted on SSL server.
Can the problem be in the code of the application? I tried both - using the init <script> proposed in facebook documentation and removing it, doesn't seem to change anything.
I had the same problem. Only found a few people complaining and saw that this wasn't working anywhere else either. I knew it was working a few months ago.
Anyway: Today it suddenly started working again. There's probably nothing wrong with you app. (Though age and country restrictions can still lock it down.)

Facebook Likebox Plugin Stopped Working?

Has anyone else seen any issues recently with the Facebook Likebox Plugin? One of my client sites has stopped displaying posts and has done since sometime last week at least. The specific plugin is here: https://developers.facebook.com/docs/plugins/like-box-for-pages/
Currently even Facebooks own demo page isn't working for me in Chrome (PC, version 31.0.1650.57 m), it displays nothing? Chrome is logged into my Facebook account.
In Firefox the demo is working but my client page placed in the devloper site is not displaying posts. I know Facebook can change privacy settings (it's caught me out before!) so I took a post off the client page and put this into the Embedded Posts plugin and it displayed correctly so there are Public posts (in Firefox, again no display at all in Chrome for me, not even with the Facebook example).
I am not logged into Facebook in the Firefox Browser but am in Chrome, using the Facebook Plugin site in a Chrome Incognito Window does give the same results as Firefox, displays example data but not posts for client page.
Does anyone have any ideas what could be causing this? It certainly highlights how aware you have to be when you rely on 3rd parties!
The facebook page might have to change country restrictions. If you don't see the box on a certain browser check to make sure you are logged into facebook on that browser.
This article explains what might possibly be your problem.

Facebook Mobile page tab error: This page is for an app that doesn't work on mobile devices (tried ref=ts)

Previously I was able to get to my app on my Page Tab on mobile devices by appending ?ref=ts to the end of the app url on the page tab. Suddenly this has stopped working and i am now getting the following error message when trying on the iphone/android facebook apps:
"This page is for an app that doesn't work on mobile devices. Please try visiting it the next time you use Facebook on your computer"
Has anyone come across this issue and does anyone know what I can do to solve this problem please.
I've used this in the past as well and just realized it was no longer working. I found a little work around but who knows how long it'll work.... I created a bitly link and redirect through there. Worked for me.

IE stuck at permissions request

I have a desktop app that was previously working. I call the FB app with: https://www.facebook.com/dialog/oauth?client_id=401292276603778&redirect_uri=https%3A%2F%2Fwww.facebook.com%2Fconnect%2Flogin_success.html&scope=manage_pages%2Cpublish_stream%2Cphoto_upload&response_type=token&display=popup
Recently, this has been getting stuck in IE at the permissions request page. No matter how many times I hit the "allow" button, it stays on the permissions request page. It doesn't get stuck in Firefox or Chrome. But since the desktop app uses an embedded IE browser, I'm now stuck. There's been no code changes on my end and I estimate the problem arose over the last week.
We're experiencing the same issue here.
It appears to be across any site - we've tried on Vimeo.com as well as our own and we can replicate the issue on each site.
The steps we're taking to see the issue are as follows:
Ensure you have a Facebook account that has never been used on the
site before
Ensure you are not logged into that Facebook account
Visit the website, click the Facebook login button
You’ll go to Facebook, log in
It’ll then show you a permissions screen with a button to Goto App
Clicking that button just results in an infinite loop where the page reloads and you see the same thing again
The issue can even be replicated on Facebook's own page on the developer site - http://developers.facebook.com/docs/reference/plugins/login/

Facebook app canvas fbml loading blank page

I developed a facebook app with fbml canvas.
Sometimes for me it loads a blank page (say 1/10 times). For a user in another location it is always loading blank page.
Is it a problem with facebook or my hosting?
Please help me out to resolve this problem.
Thanks in advance.
It most likely is on the facebook site. If it was a fault on your side, it would always have come as blank. Sometimes facebook servers go down, and you see blank pages. I have developed a number of facebook applications and unfortunately this problem happens with those apps just as well. So don't worry, it is there with the facebook itself.
