My PlatformPro site seems to be working fine. I'm still in the development/setup phase, but haven't noticed anything unusual in behavior except what appears to be a couple of bugs. But I have noticed the following error message at the bottom of the Pagelines Section Control under "Sidebar Wrap":
/wp-contentpath/themes/platformpro/core/library/class.template.php on line 534
I had the sidebar wrap set with the Tertiary sidebar, and then decided I didn't need it so I pulled out the Tertiary sidebar and it is currently empty. I suspect that this is the cause.
