thank you for purchasing Caboom Theme and sorry for the trouble.
I saw on your page that is theme that installed incorrectly, so the styling files will not be loaded. You can try it: go to WordPress admin panel, click on “appearance”. Now you see more than once “CaBoom” theme. Unfortunately this can happen if you install it directly from the hosting provider.
If you like you can send us you login for your WordPress installation send (info @ 7theme), then we install the theme again for you. Do you also have FTP login data? Then it goes faster …
Sorry again for the trouble!
