Possible issues?

Hi

The other day I was running my site in debug mode and noticed the following warnings being displayed:

Deprecated: Required parameter Sis_ script follows optional parameter list in

Forgive me if these issues have been addressed in any recent updates. I have been away on holiday. Thank you.
