Google Doc Viewer shows “No Preview Available”
<p>I'm using google document viewer to open my documents which are hosted in a Apache tomcat server. I've used this for several months and it worked pretty well. Now suddenly it gives me <code>No Preview Available</code> error even though all the files are in the same place. I didn't do any changes to the server.
The file has <code>0775</code> Permissions. What can be the problem?</p>
