From the link I sent you:

---------------------------------------------------------------------
if you do a Google search for "Creating default object from empty value" you'll find dozens of similar reports for lots of different software, along with various hints/tips as to how to rectify/hide the problem.

It *is* just a 'warning', and as such it won't affect the code functionality in any way,

Looking at this another way, the 'error' will/should only be reported if the PHP log level has been set to ' E_STRICT', which *isn't* recommended for a production site.
