Hi, We are using BugTracker.net to Track Bugs
It has fairly almost all features one need to track issues related to development and above all its free. Highly recommended after using it for almost 1 year.
We were facing a strange bug in it from quite a few time.
Whenever we try to add attachment to issue, it always failed with message “invalid id”.
After a bit of Google, we found following solution here :
In add_attachment.aspx. file remove attribute action=add_attachment.aspx from the form tag.
<form class=frm runat="server" enctype="multipart/form-data" action=add_attachment.aspx >
<form class=frm runat="server" enctype="multipart/form-data" >
Happy Bug Tracking
