Yes, well dont do anything for the moment, I will take a closer look, I got servera fixes to apply, and on my install it behaves sometimes like yours.. so I will see how to fix it. (But you will have to wait a week or so..)
As to the Fix.. thing.. the strange modifications in the template, its removed now on your test site.. but it should be on your live site.
It would be interesting to know who did that (it was certainly NOT malicious code) because it seems to be a fix for an older version applied by ??? you should definetly know who is modifying your master templates.!!!
