Hello there,
I just recently moved my site to a new server (IIS10) and am now greeted with "Upload failed due to a configuration error" when uploading attachments to my Wiki: https://gyazo.com/868ec55c2d068b4647056057a0c7cb48
What am I missing?
Thank you!
You can try the upload using a forum admin account to get more information about what might be wrong in your configuration. The specifics of configuration errors are not given to non-admins.
The following are possibilities. Without trying the upload yourself, you could investigate them all:
- The wiki attachment directory does not have the correct file permissions for PHP to read/write uploads to it (maybe wrong chmod or outside open_basedir).
- Unlikely that you would be allowed to access the uploader in this case, but can also happen if PHP was compiled using --disable-fileinfo in its configure line. PHP would need to be recompiled.
- The upload is an image file, but it does not contain valid width/height information.
- The upload is an image file that is larger than thumbnail size, but there was an exception while trying to read/write image metadata. If you are lucky, the exception and related messages might appear in your logs.
- The partition that contains the wiki attachment directory is full, so it is not possible to write to the file system.
Starting in 4.0.21, the following would also fall under this blanket error:
- The wiki attachment directory size already exceeds Options > VaultWiki: Content Types > Maximum Disk Space for Wiki Attachments, or the size would exceed this amount if the new upload is accepted.
Hi,
Thank you. I get the following error:
However, the IIS user (IIS_IUSR) has read/write permissions for the entire internal_data path and the disk quota is not exceeded.Code:Failed to write file. Check disc quotas and permissions for the path: D:\inetpub\wwwroot\domain.com/internal_data/vw_attachments/c/5/13/full.vw
I already applied the fix for the "written" variable.Code:Server Error Log

I suspect this is occurring because of a thumbnail error and it is incorrectly giving a disk quota message. In vault/core/controller/dm/attach/file/vw.php, find:
Before it, add:Code:$this->instance->set_info('canhavethumbs', $canhavethumbs);
If this is not related to file system permissions, then this change should give you more information.Code:if (!empty($errors)) { foreach ($errors AS $error) { $this->instance->error('Thumbnail error: ' . $error); }}
Code:Thumbnail error: vw_attach_thumb_failed
vw_attach_thumb_failed means that the image processor was not able to successfully resize the image file.
# 1 Does this only happen for one image or only some images?
This might be because the image file is damaged, because there is a bug in the image reader, or it might be because there was a problem preserving the original image metadata, which some laws require. If the metadata cannot be preserved, VaultWiki will reject the image rather than allow an upload that potentially breaks a law.
#2 Are there any error messages in XenForo's Server Error Log that are created when this upload fails? If there are no clues here, please email the image you are having trouble with to:
So that we can investigate what the image library sees when this particular image is uploaded.Code:support at vaultwiki.org
This only happens for a single image so far. I've forwarded it to your support mail.
I've received the image and am looking into the issue. If there is a bug, I think it might already be fixed in the next version because the image is accepted when I upload it to the dev board. But if you did not see any messages in your Server Error Logs page, then maybe we can make some improvements to the error reporting in the image module.
