I updated the template to the latest version of wordpress. And I’ve noticed that the slider for each of the work of the portfolio, it not work well. Each slider has 4 images, but the slider does not go in the second image.
Please make sure that you are using the latest version of the theme as well. If not, please login on ThemeForest with the account you have purchased Angular theme and go to Downloads section to download the latest version
