Issues with theme display after update.

Hello,

I have updated my Hueman theme to the latest version of wordpress and since then I am facing lot of issues. The responsive behavior of theme has gone. Second Earlier my header banner was fit to the size but now there is some space left at the top left hand side of header banner. Could you please look into this issue and provide me a resolution.
