Bug Images can't be uploaded (but subfolders for userid are created)

I tried and same problem wit the default skin.
My admin userID is 71.
The script creates correctly the subfolders in /forum.egcommunity.it/dbtech/gallery/images/upload/1/7/1/ with folders wm, full and thumb, but inside nothing exists.

That's a bit abnormal. Usually it's a permission issue but that would keep you from creating folders as well as images.Can you tell if the folders are being created as the same userid/group as your ftp account? Sometimes the server is setup so that php runs as a different user that doesn't have access to write some things. If you want me to troubleshoot it I'd need to get a temporary acp account and temp ftp access.

For security reasons, we recommend you create a new FTP account only for DBTech support, then disable or delete it after we have both confirmed the issue has been solved and there are no further issues.

The same applies to AdminCP accounts; they should ideally be temporary accounts created for us only. If we have created an account on your site already, you can optionally boost that account to Administrator and then de-admin this account once the issue has been solved.

If you use a .htaccess password protection for your AdminCP directory, it is recommended that you create a new authorised user for DBTech and remove this user once the issue has been solved.

Please test any temporary accounts you create to ensure that the FTP account has access to the forum files, and that the AdminCP account can access the administrative controls for the product we are assisting you with.

Ensuring this is all in order before submitting the information will significantly speed up the process of assisting you. We will alert you via PM if there's any issues with the login information you have provided.

When sending the PM, for your security you should also un-tick the "Save a copy in my Sent Items folder" checkbox. When the access details have been received, we will delete the PM from our inbox. Ensuring you have not kept a copy of the PM reduces the risk of security breaches.
