Thanks for updating the thread.
I checked the portfolio page and the code that should get pulled to display the images and other details are not showing up when I inspected the page in dev tools.
I would suggest you to try reinstalling X Theme and see how it goes. Try to delete the theme from Appearance > Themes. After that download a fresh copy of X Theme from members area or Themeforest.
Once you have downloaded the theme, follow the instructions mentioned in our Theme Installation and setup guide to install X Theme.
In case the problem is still there, then please share FTP login details in secure note. We will need to take a closer look at the setup.
