WPyogi on "parse error"

@sanver, next time, please start your own thread as per the forum rules.

In this case, both of you need to manually deactivate the theme you are using - use FTP or CPanel to access your site files on the server and rename the theme causing the error.

wp-content
    themes
         accelerate.HOLD
         graphene.HOLD

Then ask the theme developer for help with the actual error.
