In Tiki 3.x it is possible to upload multiple files at one time to any file gallery by one of two methods:
1. Keep clicking the "Add" button and add select multiple files for uploading. Then finally click the "Upload" button.
2. Select a zip file to upload, and check the "Unzip" checkbox.
In Tiki 4.0/4.1 this feature is broken. The resulting behavior is that the upload progress-indicator (spoked-wheel animation) runs forever, and the Apache server must be restarted before the user can continue to upload any other files after the failed attempt at multiple-uploads.
For purposes of data/file migration to Tiki, this is a serious issue.
I'm not much of a PHP programmer, and I suspect other Tiki users are not either...so checking out the latest code from the head of a branch is probably not a great work-around (in general).
To help developers solve the bug, we kindly request that you demonstrate your bug on a show2.tiki.org instance. To start, simply select a version and click on "Create show2.tiki.org instance". Once the instance is ready (in a minute or two), as indicated in the status window below, you can then access that instance, login (the initial admin username/password is "admin") and configure the Tiki to demonstrate your bug. Priority will be given to bugs that have been demonstrated on show2.tiki.org.
