I have installed drupal 8.0.2 on my hosting for testing purposes. I am using Zircon template and installed TB Mega Menu 8.x-1.0-alpha1. After installation, on page: admin/structure/tb-megamenu, when I click any of button, I get the following error:
The website encountered an unexpected error. Please try again later.
by searching google, I came accross with a solution: https://www.drupal.org/node/2623306
But as a new to drupal and environment, I do not know how to do it. I have never tried patching before and most importantly it is the solution for the case.
If patching is the solution, which program should I use, how can I accomplish this step by step?
