All of a sudden, on one of the Wordpress sites, when I try to upload image I get the message: "Missing a temporary folder." Error log for the website shows: mod_fcgid: stderr: PHP Warning: File upload error - unable to create a temporary file in Unknown on line 0, referer: http://mywebsite.com/wp-admin/media-new.php I tried this solution (didn't work) Also tried custom php.ini settings under webiste options (ISPConfig) upload_tmp_dir = /var/www/clients/client14/web27/tmp upload_tmp_dir = /tmp didn't work either. Any ideas how to handle this issue without compromising security of the server?
