I have an wordpress installation, which worked fine up until recently. I somehow can't upload any images. They won't show up on the server, and when I upload the manually via FTP wordpress ignores them and acts as if they are not there.
I already tried a few different solutions I found on the web, like adjusting the permissions, but it doesn't seem to work. But the image is uploaded somewhere, because when I click on edit Picture it shows it. Although the src of the image is some temporary folder.
The debug mode also shows nothing. No errors.
I downloaded a fresh wordpress ZIP and replaced all the files in the FTP with the ones in the ZIP, except for the wp-content folder and wp-config.php
Still not working
This is the src part of the img tag in the image edit screen:
