SID-01418: Cannot add attachements with TWiki 5.1.1 and IE 8

Status:	Answered	TWiki version:	5.1.1	Perl version:	both VM-5.1.1 (5.8.8) and 5.8.8
Category:	CategoryAttachments	Server OS:	both VM-5.1.1 (centOS) and RH 5.7, 2.6.18	Last update:	13 years ago

The problem is attachements cannot be added using Internet Explorer 8 and TWiki version 5.1.1. The failures are the same in TWiki-VM (as downloaded from the TWiki site) and RedHat (manual installation).

These are the steps I am following:

1) Log on as a registered user 2) Create a new topic 3) Click on Attach. 4) Browse for an attachement. 5) Click Upload file. 6) No warning or messages are issued and the browser returns back to the topic. 7) Clicking on Attach does not show any attachments and nothing is uploaded to the server.

I have verified the ownership and group settings are correct for all of the twiki content.

The problem does not occur when a non-Internet Explorer browser is used.

An error is being issued in the RH flavor running apache as shown in error_log... upload: Use of uninitialized value in concatenation (.) or string at /var/www/twiki/lib/TWiki/UI/Upload.pm line 423.

The same error is issued in the VM flavor of TWiki at /var/log/httpd/error_log.

Debugging lib/TWiki/UI/Upload.pm shows the file list in $query->{uploads}{$_} (line 229) appears to be empty -- although I'm not a perl expert by any means.

Discussion and Answer

I have confirmed this issue also exists with the TWiki.org sandbox web.
