Blank Page Error still exist!

First the website was having an http 500 error and i tried to resolve it.Now the blank page error exist.My username is epiz_20465917 and website url: Help

The website does return a 200 response code meaning the script doesn’t crash. Can you login to your Wordpress admin area and switch to the default theme or disable some plugins to see if that solves the problem?

No i cant even login the wp-admin .The wordpress admin also shows the same blank page error
