[wp-hackers] get_user_meta returning empty string

[Muro, Matthew]

Never underestimate the power of posting.  The problem ended up being that someone using a different $table_prefix other than "wp_" wouldn't have the meta_key "wp_capabilities".

Let me know if I'm jumping to conclusions here, but I'm able to reproduce the error.

Hey guys,

I'm using the get_user_meta function to grab the wp_capabilities of a user, but in some cases it's returning an empty string instead of an array.

Here's how I'm using the function:  get_user_meta( $current_user->ID, 'wp_capabilities', true );

Depending on the server, a successful response is something like array(1) { ["administrator"]=> string(1) "1" } or array(1) { ["administrator"]=> bool(true) }.  However, the cases where it fails returns this string(0) "".

According to the Codex, it should at least return the value I'm looking for.  What would cause get_user_meta to return an empty string?

Thanks,
