Can't upload a new image to an article

[seadhna]

Hi, all of a sudden, I can't upload any image to an article. I get a confirmation message if I click Apply but the image has disappeared. I can select an image from the dropdown list, but I can't upload a new one. I have reuploaded every single file from the CMS to the installation but the problem persists. I can't think what I might have done to cause this. Have you ever seen this issue before? Could it be something in the .htaccess file?

If I try to upload the image via the Media Manager, I get the error message "No file uploaded". This happens in any directory and for all file types: JPG, PNG, PDF

Many things may be wrong. If you can't  upload anything most probably you are out of free web space. Check you web hosting limits and your current disk usage.

Yes, it seems to be a server-related issue rather than Elxis. I just migrated the same installation to a new server and there is no issue. Thanks!
