Sociable/Stumbleupon problem

I have similar but slight variation on the same problem. Mine comes up as

The requested URL /url/https://www.blackjackskanz.com/index.php/?p=31 was not found on this server.

For me, I think it is the /url at the start that is breaking it. At first it was droping the /index.php/ before ?p=31 which I solved by changed the URL to my blog under Options from https://www.blackjackskanz.com to https://www.blackjackskanz.com/index.php (not the URL to WordPress, that would do bad things).

But I am still getting that strange stray /url/. From what I read from another post, it looks like a problem with WP 2.2 and Sociable but the author is not replying to emails.

Hopefully the author updates or someone shares a solution. If you find out the solution let me know.

I’m still having this problem, does anyone know how I can fix it?

Had the same problem. This helped:
WordPress Sociable Fix

From the page:

I’ve spotted a bug in the current version of the plugin (version 2.0) which prevents people from bookmarking your posts to StumbleUpon. If anyone tries to bookmark a page to StumbleUpon they will be taken to an invalid URL. The problem is with the following piece of code in sociable.php

‘StumbleUpon’ => Array(
‘favicon’ => ‘stumbleupon.png’,
‘url’ => ‘https://www.stumbleupon.com/url/PERMALINK‘,

To fix the problem, change the above code to this:

‘StumbleUpon’ => Array(
‘favicon’ => ‘stumbleupon.png’,
‘url’ => ‘https://www.stumbleupon.com/submit/?url=PERMALINK&title=TITLE’,

You may want to temporarily disable the plugin whilst you make this change.

Works like a charm! Thank you dronerebel.

Thank you for this fix, awesome.

I “hijacked” the Sociable plugin for a new release, and fixed this as well as a lot of other stuff.
