Error 500

Hello !

I have a HTTP Error 500, when i activate the BlackFyre theme ! 🙁

My test in localhost is ok, but didn’t work once i upload it on web version.

Even if i do a fresh start of wordpress, at the moment i use blackfyre, it say Http error 500 and i don’t understand what to do. I have try to chek the .htaccess file, to rename it, to remove all plug in… nothing seem’s to work.

What should i do ?

Thanks by advance
