Hey Davshirley,
now I understand the issue, sorry for misinterpreting your first message :)
After some troubleshooting this is what the situation looks like to me: the slider does appear on the front page (see screenshot), yet when one clicks on any other page (e.g. “Contact” and then clicks “Home” to return to the portfolio, the slider is not rendered. If, however, we refresh the page, the slider is again displayed normally. This pretty much looks like (in fact, I am 90% sure that it is) a Javascript issue here, either in the theme or in the slider, or between the two of them, and I need access to the back-end in order to find the cause and fix it. Please provide your WordPress login and password by sending them to support@satoristudio.net, and I will look deeper into the problem.
Sincerely,
