I updated to 3.7.13 and my header was not showing and my admin bar was also not showing. I save settings and header & footer shows now.

I still have one problem:

(1) admin bar not showing (edit: this is resolved, I forgot to save footer options)

(2) metaslider plugin (http://wordpress.org/plugins/ml-slider/) is not showing on my frontpage. The code is still there. Preview in the plugin also works, it just doesn't show on my homepage (www.bartvandermark.nl). It should show just below the header (logo & menu).

All is resolved, also the metaslider plugin appeared after I saved footer options...
