Hello,
Thanks vitasis, the output you've provided is telling us what's going wrong, we just need to figure out why.
The form has 2 key values:
value1 and value8
by default, both are blank, and both are hidden in the form.
value1 is for usernames
value8 is for domains
When either button is clicked, a JavaScript function will set the value1 or value8 to the "value" typed in (the name of the actual search field).
Now in the url you've pasted, value8 is holding the username.. which means the form thinks that the "Domain" button was clicked. I'm not sure if this is true or not. Going over the code, the "logic" is:
if user, set the value1, else set value 8
So, it's possible that the check to see if user was selected is failing.. I'm not sure why (perhaps 'type' is a reserved javascript name).
The fact that this is random makes it quite tricky to debug. Now we know what we're looking at, for anyone who is affected by this, see if you can spot any patterns in the setup conditions to duplicate it..eg: if you can get it from logging in and submitting it right away, or if you need to use your browser's "back" button to get it to cause the error... etc... I'm having troubles getting it to trigger the issue at all.
