I've made numerous Facebook apps and attached them to fan pages no problem but for some reason I can never access the apps via the canvas page directly.
For example: https://apps.facebook.com/cashcallwatch/
is coming back with a URL errors, absolutely no idea why. I've looked all over for a solution / explanation but havent been able to figure it out. Any help is much appreciated.
If you look at the Page Tab iframe you will see that it points to: https://www.cashcall.tv/CashCallFacebook/
That url is to a directory, you probably want to change the Page tab url to any of your php/html documents, for example: https://www.cashcall.tv/CashCallFacebook/facebookwatchandwin.php
If you can't point directly to a document, just rename facebookwatchandwin.php to index.php and it will probably work since it will be served as the default document for that directory.

I've came across this page https://www.tumblr.com/examples/share/sharing-links-to-articles.html which shows a possible way to customly create a share URL for tumblr.
Simplified version of what they have:
Click to share
http://jsfiddle.net/m5ow6bhs/2/
This will take you to the log in page or straight to the share page if you're already logged in. However, if you change the http%3A%2F%2F part to a simple http:// it will now load to a "Not Found Page". http://jsfiddle.net/m5ow6bhs/3/ What the hell Tumblr?
Do you guys have any idea what's going on or what's the correct code to share something to Tumblr?
Cheers.
As with most share services, the URL should be passed as an encoded string. This supports the OPs comments about http%3A%2F%2F(encoded) and http:// (raw).
Tumblr provides variable transformations in the theme operators to handle encoding, but sadly it doesn't work with custom variables.
One quick solution is to drop the http:// part. Example: http://jsfiddle.net/L9jd8dhz/
I have discovered as of recently that the share URL needs to be updated as such:
https://www.tumblr.com/widgets/share/tool?shareSource=legacy&canonicalUrl=<-urlencode(share_url)->&posttype=link
The &posttype= seems to be a new requirement to make the share work correctly.
I'm sharing content from a website and every time I paste the link into Facebook it says 'page not found'.
Sometimes it works when I manually add the 'www.' in front of the URL in the address bar.
EXAMPLE
Shows page not found:
http://roundreviews.co.uk/reviews/speakers/native-union-monocle-speaker/
Works when you manually place www. in front:
www.roundreviews.co.uk/reviews/speakers/native-union-monocle-speaker/
I honestly have no I idea why it's doing this, any thoughts on how it can be fixed on the web side?
Also...
I have tried with the link below with both the www. and without yet it doesn't work with either of them, this is all very strange. This is the only link I have tried and it doesn't work with both:
www.roundreviews.co.uk/microphones/spark-digital-microphone/
Any help is much appreciated, thanks.
For me what it worked was to access the Facebook Debugger, as Goose said.
I saw that the scrape was about 12 hours ago, looks like it fetches the first time and saves it as caché or whatsoever...
What it worked for me is to debug the url, then click "fetch new scrape information" after the previous information has been shown.
Hope it works!
For those running across this today, you might find that you also need to verify your domain and link it to your page.
To do this you need to
Set up a Facebook Business Account
Add your page to the business account
Verify your domain (using DNS TXT or adding a page facebook gives you)
Under domains, connect your page as an asset of that domain
In trying to create an "object" page for my first facebook app, I've run into some difficulty. I followed Facebook's Open Graph Tutorial nearly exactly.
After creating an "object" html page with the appropriate <meta property="og:... tags I tried running the URL through the Debugger Tool as suggested in the tutorial but I'm given the following error:
"Facebook URLs aren't scrapable by this Debugger. Try your own."
This page is in the same directory on my company's linux box as the canvas page, and is certainly not a "Facebook URL". If it matters, I'm using an IP instead of a domain name: xx.x.x.xxx/app/obj.html
...
I continued the tutorial anyway, but ultimately it does not seem to want to post a new action/object (is this even right?). I did however manage to get something to work, as in the app timeline view I apparently actioned one of those objects a couple hours ago. I assume this happened when I was pasting curl POST commands into the terminal.
I'm pretty new to the whole open graph, and facebook APIs, etc., so I'm probably operating under false assumptions of some sort, and I've been all over trying different things, but this error seems pretty bizarre to me and I can't seem to resolve it.
UPDATE
I just took the object page and put it on my own personal shared hosting acct. The debugger worked (inexplicably) fine on it, but I couldn't go too far since it's a different domain than the one authorized by my app.
Make sure og:url inside your html page does not point to facebook.
Also, make sure to look at the open graph protocol page (to see you formatted the og tags correctly.
Also, make sure the page is accessible to everyone, not just yourself.
Without knowing the URL it's hard to be sure, but it's most likely that your URL is either including a og:url tag pointing to a facebook.com address, or a HTTP 301/302 redirect to Facebook instead
I've been at this for almost 3 days straight and now I can't even think clearly anymore.
All I'm trying to do is to get my featured image thumbnail to appear when I paste the link in Facebook.
I'm using the Wordpress Facebook Open Graph protocol plugin which generates all the correct og meta properties.
My thumbnail images are 240x200px which respects the minimum requirements and also respects the 3:1 ratio
I've made sure there's no trailing slash at the end of my post URLs
When I use the Facebook Object Debugger, the only warning is in regards to my locale, but that shouldn't affect it.
Facebook appears to be pulling the right image, at least the URL is correct, but the image appears as a blank square
I've gone through pretty much every thread I could find in forums, but all the information available is about using the correct og tags, which I believe I'm already doing.
Thank you very very much for any help, I'm desperate!! :)
You can troubleshoot the OpenGraph meta tags with the Debugger https://developers.facebook.com/tools/debug - this can at least show if you're using the meta tags properly and if Facebook can 'read' the image.
I finally figured out that the root of my issue was the fact that I was using an addon domain (which is really a subdomain being redirected to the top level domain) and I read on eHow (of all places :) ) that Facebook has trouble pulling data from redirected domains.
Not sure if there was another way around it, but I simply ended up creating a seperate hosting account and everything is loading properly now.
one problem youre going to run into testing is that often the first time your page or post gets liked, fb keeps whatever img it finds in your meta tags or by searching your page. so, you'll keep changing your img meta tag and still it wont show the right pic. it's very anoying. One way to get around it is to change the slug of your post. now, it has a different url and to fb, it's a different page. The downside is you lose all the likes that go with your orig url. Not a problem with a new site.
I ended here googling another problem. Maybe this might help someone:
Please bear in mind that the facebook scraper works asynchronously and will need some time (during my tests around 10 minutes) to be able to display an image after seeing it for the first time.
For more information, here's a more thorough answer on a similar problem.
Indeed, as Andy Wibbels points out the FB debugger is a really handy tool.
I faced a similar issue with a server's og:image tag pointing to a secure subdomain which actually mirrors a CDN server,
<meta property="og:image" content="https://subdomain.pathToImage.jpg" />
<meta property="og:image_secure" content="https://subdomain.pathToImage.jpg" />
The FB debugging tool allows you to see the errors that FB encounters when trying to pull the image.
In my case the subdomain was not registered under the SSL certificate used by the HTTPS protocol. Hence FB was getting the following error,
Curl Error : SSL_CACERT SSL certificate problem: unable to get local issuer certificate
I have successfully setup an iFrame based App using the Javascript SDK, and we are trying to enable it on a Page Tab.
It seems Facebook has changed some things lately, because the app breaks when added to the Page Tab. I even went as far as making sure that all external scripts were included in the main index.php file, and that the body tags were taken out.
No, I'm trying to find out if it is even possible to use methods such as the stream.publish within a Profile Tab at all.
It seems like it isn't. As far as I can tell, you can no longer use any social methods on the Profile Tab.
Here were two related articles on the subject:

If anyone can confirm or deny this, it would be a huge help. The Facebook docs are just all over the place.
Here's a link to the working App Canvas as it stands now: http://apps.facebook.com/votetesting/
I know that on tab pages, you cannot do any JS until the user clicks on something first. Maybe that is the problem.
