Un-suppress warnings?

I don't know - WordPress is not a specialty of mine. It might come down to you needing to deliberately create errors in various places until they go away, and then trace it from there. Integrating two large-scale scripts like this can be a pain to see which is controlling what, especially if they're not separated into their own folders and such.

It's possible WordPress includes it's on set_error_handler() function as well.
