Yes I managed to update the theme using FTP.
With the shortcode I still have issues. Please have a look at this page https://escortkenya.online/person/piere/ A closer look at the sidebar please, yes it shows all from the category but so small that the mouse over is so big that it’s not usable. Rather would have them listed underneath eachother.
Than the picture issue. If you look at this page: https://escortkenya.online/smooth-slider/ the pictures I resized on Photoshop to the same size and quality. Still the theme does that with it.
