Plugin breaking my theme

Hi, I recently updated a clients site to the newer WP version to 4.7.5 so I can update the plugins, theme etc…, since I did this, when I activate the Theme the screen turns white, when I deactivate the plugin everything returns back to normal. So I rolled back my WP version to 4.4.1 and now because I updated your plugin, I get the same white screen. The theme I am using is JOBSEEK by Coffeecream , you can view this on Themeforest.
Can I roll back the plugin with the older version ( Nov 2016) until we can figure out where the error is occurring from? Please point me in the right direction to select and download an older version of your plugin. Thanks
