title: Visual composer backend editor not working with U-design theme older versions
body: <p>So I had this issue for quite a long time on my client's website which was running u-design theme version <code>2.12.3</code>. The backend editor, screen options, or any other drop down was not working. There were multiple JS errors in the console and whole website was messed up. I have finally found a solution after a month of brain storming. Posting this as a solution to help whoever encounter this issue.</p>
