I have some themes that I have created by modifying _s (underscores) themes and can't get the live preview to function to work on my live site. When trying to view any of my modified themes generates an Internal Server Error.
Live Preview works for my themes on my local development site and themes by others work on both local and live sites. I tried an unmodified _s theme and it works so it is obviously something about my theme and the live site, but not sure how to track down what function(s) are creating the problem.
Any help to track down what is going wrong would be greatly appreciated
