UBB.threads PHP Forum Software Community Forums UBB.threads 7 Installation and Upgrade Support File Manager problems

Running v 7 on Windows 2000 server.
Configured attachment directory and full path correctly, privileges for the web server user set correctly ("test directory" can create a file in the attachments folder).

The file manager allows to add/remove files.
Links to the attachments show up in the posts.
No error messages or anything.

However:

Clicking on a link leads to a "page not found" error message.
The URL is correct, and the file name shown is the name of the file I have "uploaded" via the file manager.

But the file is not created in the attachments folder.

When I replace the file name in the URL with the name of a file that exists in the attachment folder, it works.

DOes your php.ini allow uploads? Are you trying to upload a file larger than what php.ini allows? Default is some real low file size like 2 megs or so. Php does not return an error if the file is too large, it just quietly discards it, which means threads doesn't know it failed. The scenario you describe is pretty much what happens if you're uploading a file larger than php itself currently allows.

Thanks for helping!

I control the server and hence the PHP ini.
The allow_uploads is ON, the max. upload site 32M.

The upload test files are around 10 KB only.
I have the "inline images" option turned off.

"Old" attachments (uploaded with the old forum and migrated by me to the new forum) work. It's only the new file manager fails to upload files.

Ok, so it's not actually creating the uploaded files in the folder? Do you have avatar uploads turned on? If so, are those working correctly? If not can you try turning those on to see if those work. That will give us more info as if it's a general PHP issue or something else.

Hi, Rick

We're getting nearer.

I cannot upload Avatars via the Control Panel. The error message is "We could not move the avatar into the /images/avatars/default directory..."

I also checked uploading graemlings and forum icons, and this no longer works, too. I have been able to upload graemlins and forum images a couple of days ago when I migrated the forum.

Something I've done after the initial migration caused problems.
I checked the security on the web in IIS and the file system, and the permissions for the web server user for these folders are OK. They are inherited from the web root of the forum down to the lowest folders.

I refreshed the security down to all folders, without a change.


The "Permission Checks" in the control panel also returns all folders with a green OK.

I've tightened the security on this web site a bit, like for my other sites:

register_globals = Off
allow_url_fopen = off
safe_mode = On
display_errors = Off
open_basedir = d:\web

Any special setting I should check?
I've also used SysInternals FileMon to check what's going on in the file system, but except from some failed looks for the newly uploaded file ("no such file") there are no errors or privilege issues. The no such file error is caused when the control panel checks for the file after the upload. But since the upload failed, this error message is to be expected.

First of all I would turn safe mode off.

Does the various images directories have at least read and write permissions enabled?

You might also like to set up a copy of your php.ini file in case this shows something up.

I agree, I think the issue at hand is that safe mode is on; I believe there was another thread somewhere about a way to move things with it on, but it's more trouble than its worth

Yep. Tried that already. No difference between SafeMode=ON/OFF.

When I look into the doaddgraemlin.php page and echo out the


$graemlin_temp is empty. It seems that the file is not uploaded.

Problem solved.

Two things prevented the uploads without any error message:

1: PHP requires that the user under which the web site runs as write access to the "default" temp folder, which is in my case c:\windows\temp

2: open_basedir must not be set

Perhaps there is a configuration setting which gives me more control about where temporary upload files are written to?

I think it should be in your php configuration, if not then your webserver configuration.

its in the php config file.. you set whether you want to upload and where the temp files go.

si:

; Temporary directory for HTTP uploaded files (will use system default if not
; specified).
;upload_tmp_dir =
