How do I deleted an ENFOLD theme from my Theme Library?

I launched a new website, scmjf.org.

I installed the themeforest zip file for ENFOLD, which i recieved a few months ago.

The theme loaded into my library of themes; i activated it; upon activating it, i checked my website: It was a white screen.

Nothing.

I was advised to download a new copy of the theme from my Envato Account. I downloaded the new copy onto my desktop and installed it into the Theme Library. However, I cannot tell if this new theme overridden the existing “corrupt” theme that was in my library.

To explain more clearly, before I had downloaded the NEW COPY, I already had one copy of the “Enfold” theme in my Theme Library; the thing is, that theme wasnt working when i activated it. So, I downloaded a new copy, and installed it into the Theme Library. I can’t tell if the current “Enfold’ theme is the new copy, or the old copy.

In either case, I still get a white screen.

THE SOLUTION would be to DELETE the ENFOLD theme from my library. Once deleted, I can install a new copy, and this new copy should result in a working website when it is activated.

Please help! How do I delete an ENFOLD theme from my theme library?
