I have been following along a basic tutorial on creating a simple theme structure. I have searched quite a few articles to get an understanding and looked at debugging tips, however I am at a loss, probably due to me limited knowledge base. At this stage I had downloaded bootstrap css and js folders. This is on a local server and I don't have any plugins installed or activated.
After quite a number of error messages I have come down to this one. Sorry, I don't remember what changes I made in the functions file to get to this one.
