when i install a theme it appears to be completely different and doenst shows contents which are supposed to be there. And nothing happens if a do changes from dashboard appearance and customize. kindly help! [![see here]]
From the two screens you posted, the installed and the activated themes are different.
It seems you are showing SKT Strong theme (activated) and Enlightenment theme(not activated).
Which one is supposed to show?
even if i install a theme and activate it, it dont have the desired design and contents
Do you mean that it doesn't have the "Worth a Thousand Words" and "Elements" content? If so, that is just part of the theme preview. It will never appear when you install the theme.
