Facebook mobile web returns 'Your link could not be found' when sharing a URL

Question

When users try to share a URL on facebook mobile web, sometimes the page returns the following message: 'Your link could not be found' and a text input to manually insert the URL

1. Sharing URL that works: https://m.facebook.com/sharer.php?u=http://dishenvy.com/dish/pollo-garnachas-gran-electrica-brooklyn

2. Sharing URL that doesn't work: https://m.facebook.com/sharer.php?u=http://dishenvy.com/dish/samgyupsal-hahm-ji-bach-new-york-

Code I'm using:

<a class="fb_share" name="fb_share" type="icon" share_url="<?php echo urldecode($shareUrl) ?>">                                               
<script src="http://static.ak.fbcdn.net/connect.php/js/FB.Share" type="text/javascript"></script>

Answer 1

Make sure the url you pass is accessible to Facebook. Not sure why, but their mobile site seems to validate the url but their non-mobile site does not seem to care. If you have code generating the link you pass to facebook and the host corresponds to a server behind a firewall or private network (such as a test or dev server), this error will often happen.

Answer 2

https://m.facebook.com/sharer.php?m2w&u=http://dishenvy.com/dish/samgyupsal-hahm-ji-bach-new-york-

For mobile view you want to add m2w to the url.

Answer 3

I think facebook check your sharing page found or not on the server. Your first url found on the server (It means first url return the page). Second url doesn't return the page. The second url return the empty page for this reason facebook return this message. 'Your link could not be found'

Click the link :

1. http://dishenvy.com/dish/pollo-garnachas-gran-electrica-brooklyn = Page found

2. http://dishenvy.com/dish/samgyupsal-hahm-ji-bach-new-york- = Page not found

So share correct url on the facebook

Answer 4

According to the debugger the two url example that you posted work the same:

• First
• Second

So I don't know how to help you with that.

What I can tell you though is that you are using a deprecated api. The facebook "sharer" is no longer supported as it states here:

The Share button has been deprecated in favor of the Like button, and will no longer be supported. Please use the Like button whenever possible to drive maximum traffic to your apps.

And here:

What happened to the old Share button?

We deprecated the Share Button when we launched the Like button, because the Like button improves clickthrough rates by allowing users to connect with one click, and by allowing them to see which of their friends have already connected.

That may be a cause for the inconsistency you are experiencing. My advise to you is to stop using this deprecated api and move to the Like button.
