Question

//on some hosts the uploads directory is not automatically created 
//on WP auto install so we create it

if (!is_dir(ABSPATH.'wp-content/uploads')) {
    mkdir(ABSPATH.'wp-content/uploads');
}

I’m trying to troubleshoot an issue in which some people who install my WP theme get an error (no description) or a blank white screen. I’m thinking that perhaps the code above could be the culprit on certain setups, perhaps depending on support for mkdir?

Answer 1

It could be that wp-content is not writable. That should result in a warning at most, though, not a fatal error.

mkdir could also be disabled by the provider in a safe mode context, but that should be extremely rare.

There’s only one way to find out really: Have people activate error_reporting() and see what the blog spits out.

If I were to shoot in the dark, I would first check whether you use any PHP 5 specific keywords (private public…..) and clients still use PHP4.
