Hard to say? If that file was out of place, it’s possible there’s others? Or maybe a plugin that’s gumming things up somewhere? Usually the best way to trouble shoot this is to start removing plugins one by one and see which one is causing the conflict. If you have no plugins and it’s still white screening, then it’s usually a bad installation from the start, a memory issue with the server, or a PHP version issue; the last two you only have so much control over.
