I'm trying to add a new product, and I'm getting a big fat blank page with an "M" on the very top left hand corner.

This also happened with another action I was doing. I was editing the paypal section, and when I clicked "save", the same blank page with the "m" came up, but it DID take the changes.

I'm not sure what's going on, but now, I really cannot add new products.

Anyone seen this before?

Thank you,

I'm working with 1.3.7
