Funny thing happened with Drupal 7.50, errors started appearing that I had no clue about. It started telling me about modules not being where they were supposed to be and about a utf-8 not being enabled.
I was immediately frustrated by this. All I wished to do was a "simple" upgrade and I'm getting hit with problems. I abandoned what I was doing and went into hiding. I have been doing drupal for coming on my 3rd year, and it seems like everytime I feel like I'm starting to get the hang of things something happens and it makes me feel like I'm back to being a beginner.
