Unsupported Trim Size

When I uploaded my file, It stated that it was an unsupported trim size. But I am having a hard time finding which sizes are supported.  Also, it stated that there were problems with my files. But didn't actually tell me which pages those are on. I believe in the old lulu, it did list where pictures are too low resolution or lines are too thin, etc.
