Troubleshooting/Fix my PHP Twitter App -- 2

I have a twitter app designed to follow users that follow specific accounts i load into a queue. It had been working for several months until this past week. I need it fixed ASAP. I'm fairly certain it has to do with the API integration somehow but I don't know how. As s side project, I've also been procrastinating the new bootstrap stuff I had created for the site. If you can do that too, you're hired for sure.
