None of these solutions work for me. I installed and it was working great for 2 days. Then I activated another plugin, and that was it. I removed all the file, reinstalled, click activate, and then just blank.
I hope there is a solution to this.

I was researching on optimizing website performance and load speed and found an interesting hint. While this is not related to the WSOD bug, it may be useful for njs7227 and everyone else using CDN.
First, if you map your CDN service or S3 bucket to your subdomain you will have redirects.
Second, browsers will prefetch DNS only for your subdomain, not the actual location of a file. You will have non-prefetched DNS lookups, it can significantly decrease load speed, especially if you have many files linked to CDN.
The solution:
Let's say you have files.domain.com.s3.amazonaws.com mapped to files.domain.com. In your HTML add this tag to your HEAD section right after the charset definition:
<link rel="dns-prefetch" href="//files.domain.com.s3.amazonaws.com">
This will tell browser to prefetch DNS lookup of this domain address, and when the actual request and redirect is made, the DNS lookup part will be skipped (it's already prefetched) making it respond faster.
Tested, it really helps.
I'm not sure yet how Amazon serves this subdomain internally, right now testing if adding one more prefetch link for s3.amazonaws.com will make it even faster.

If I had to guess, your Wordpress and Site address are both http://www.website.com/wordpress/ in your General Settings.
Take a look at http://codex.wordpress.org/Giving_WordPress_Its_Own_Directory to see how to fix the subdirectory issue.

Thanks for the suggestion Ebenchich.
I don't think this applies to me though because I am running the site from the subdirectory as well (not the root). The rest of my site is powered by Coldfusion - it is just the one directory (in the original post called /wordpress/) which is running wordpress.
I am guessing there is something in the W3 Total Cache plugin php which I need to modify to allow for this. Unfortunately I don't know how!

Same issue. is there a workaround to the issue?

Here is the solution from another user:
hanks to Milo's and MathSmath ideas, I was able to figure out a solution myself. Apparently a lot of people have issues with W3 Cache and sharing on Facebook. There's quite a simple solution to it, though!
Go to the W3 Cache plugin settings, more specifically to "page cache" and make sure to reject these user agents:
facebookexternalhit
FacebookExternalHit/1.1
FacebookExternalHit/1.0
This will block W3 Total Cache from sending cached pages to Facebook.
Personally I still have issues when using the "like" or "share" button in my blog. The "Like" button sometimes doesn't provide the right thumbnail, but I'm sure I can fix that, too. I might update this answer then. The "share" button I use doesn't work at all. I guess I need to find another code for the Facebook share button and try again. Copying the URL directly into Facebook to share something works fine now!

Firstly, I can't be sure it is this plugin with the fault, however the issue only occured after installing the plugin yesterday. Also, I have disabled this plugin only (leaving others enabled) and the issue has gone away... for now...
While I am monitoring I just wanted to put this out there to see if anyone else is experiencing the issue?
URL friv.webeden.co.uk has been injected top left hand side of each page.
Looking at a google search its happening to a lot of sites
Again I'm not blaming this plugin as I have no proof its what caused it.

Second update:
Applied the above solution with no avail and found a simple solution that works.
Go to the following link.
https://developers.facebook.com/tools/debug to determine if Facebook detects your og:image. If not, add some code.
Explanation
----
With the new Facebook Open Graph stuff, you can define a thumbnail for that page in your "head" of the form<meta property="og:image" content="[image url]"/>

weex on "AJAX calls + W3 Total Cache"
Hi, I have a question. How would I be able to utilize this plugin if I have a theme with javascript making lots of ajax calls.
This plugin is all about each request avoiding loading of wp stack for each url request sent to apache then to wordpress stack. (what would normally happen without w3 total cache)
How would I be able to access the cache data in more customized ways. a ajax heavy theme encounters this problem. i'm aware of the define shortinit as well, just fyi. If this is too vague i can try to be more specific. i hope this question makes sense.
plugin author or anyone care to give insight? thanks for reading.

is this possible or a realistic question?

I have changed the permissions back to the defaults using the command "# chmod 755 /var/www/wordpress/wp-content" but the message "/var/www/wordpress/wp-content is write-able. When finished installing the plugin, change the permissions back to the default: chmod 755 /var/www/wordpress/wp-content. Permissions are currently 777" does not disappear in the settings menu.
I have entered the command as specified in the installation guide and did not get any errors. What could have gone wrong? :-)

Well, I am a bit surprised to see this post so I come to check my site.
I checked the source homepage using Google Chrome but I found no link as you said.
You may want to check again where is the source so you can get risk of it completely. :)
