How large could a frog be?

While Prionosuchus and other large temnospondyls are definitely imposing and capable of causing mortal harm, they still adhere to a distinctly salamander-like profile. Anurans (relating to frogs or toads) seem to have not gotten any bigger than an unimpressive beachball of meager weight. Beelzebufo may have grown larger given incomplete cranial sutures but it's doubtful it grew to the size I require...

Now, how large can can a non-specified species of frog or toad be before the square cubed law makes the creature unable to actively hunt other organisms?

Emphasis on actively : The thing may be rendered unable to hop, jump, glide, climb or otherwise gallop due to physiological restraints but it must be able to chase and either swallow a man whole or rip him to pieces.

Edit: Actively was meant to be "not a crocodile mimic". Originally, I vaguely considered a creature resembling a bullfrog or cane toad but was unsure what the bodyplan would allow:

Could it bellycrawl at high speeds for short distances? Could it manage a meager hop or a full-fledged leap? Would thick toad skin help it resist injury and better carry it's physical load? Would it's tongue be rendered unable to shoot out of it's mouth due to it's mass?
