Sorry for my late response, but I had no time to investigate until now. I've open an SSH connectiont to server and made an
tail -f /var/log/apache2/error.log
, then I've tried to upload an image via webpage and I didn't receive any errors.
Then I've entered in ISPC administration page and modify PHP handler. First tried with Mod-PHP and received The uploaded file could not be moved to /var/www/clients/client1/web3/web/wp-content/uploads/2013/02.
. Then switch to suPHP and seems that now it's working OK.
