when I go to "Orders" and click on one of my test orders that are labeled "Proccessing" all I see is this:
No more infos, nothing to click.
Any idea what to do? What should appear when I click on an order?
I suggest that you check first var/log/system.log and/or var/log/exception.log as there's probably more information about what's going on. It looks like Magento crashes at some point.
You probably need to turn on logging. Go to System > Configuration > Developer > Log Settings and enable it.
Turned it on. Where should the folder be?
I'm looking at Magento > var
Can't see it
Thanks so far btw!
Now go to your orders and try to make sure that problem happens again. After that your var folder should have log folder containing either system.log or system.log and exception.log.
This is kind of suspicious; even perfectly configured Magento will now and then spill something to system.log -- are you sure you enabled logging? This is by default turned off.
