We have a serious problem with the images in the backend. It doesn't show any images when uploaded, just the filename. The uploader works but there is no picture afterwards. Also after I've chosen it from the insert picture in the editor it shows up as 'broken'. Till 2.4.1 this worked.
In the file structure (FTP) the picture is there. The permissions should be ok, 775 for assets.
Here is our PHP-Configuration:
I am having the same problem, too. I can add images through the admin panel, or via FTP. The file names are visible in the Files & Images panel listing, but they do not preview, and links to them fail with an error page (File not found). Its a troubling problem, since its hard to deliver content as all-text. Each missing image requires a thousand words.... Running SS 2.4.3.
Edit: http://silverstripe.org/installing-silverstripe/show/14878?start=0 seems to address the issue. Making the change found on the link suggested by Sean solved the issue. In short, our servers must be running PHP as FastCGI.
Further investigation reveals that the issue in my case relates to the following code in .htaccess:
Deny from all
Allow from all
Update: Removing "Deny from all" *only* resolves this issue. I see this message in the error logs of the server: "client denied by server configuration:".
Anyone have any ideas at what may cause an error with this code? I guess it is a configuration issue with my host.
