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.
ie
Change :
<form class=frm runat="server" enctype="multipart/form-data" action=add_attachment.aspx >
To :
<form class=frm runat="server" enctype="multipart/form-data" >
Happy Bug Tracking :)
