Fatal errors

Many meta keys are throwing errors on line 158 for me, as there is no value found for $meta_value[0]. I have worked around it by adding an isset check.

if( isset( $meta_value[0] ) && '' !== $meta_value[0] ) {

I’m unsure if that is blocking the post meta revisions from working or not. I’m somewhat busy today, so just hacked that in as a temporary solution until I have time to check if it actually works or not.
