Hi,

I have deployed my website to a hostgator server, no setting changed, came from a local setup on Mac OS X with MAMP, running the latest 5.7 build, but for some reason I am getting the following error:

Call to a member function hasPageThemeGridFrameworkOffsetClasses() on a non-object

I don't get this on my local machine. Any ideas as to why this might be? Something to do with case sensitivity maybe? This line appears in the following files:

/concrete/src/Area/Layout/ThemeGridColumn.php:
/concrete/src/Page/Theme/GridFramework/GridFramework.php:

Any guidance is appreciated.

Thank you
