I suppose he is still juvenile comparing him to the cricket?
The size of that cricket is somewhat big for this frog in my opinion.
I know some people feed their whites oversized food items like rats and other big stuff like that,
but the danger of impaction will grow that way. (On the otherside they keep thinking that substrate causes the impaction )

It could be me, but looking at this frog gives me a feeling that something may be wrong.

If i were you i'd send some stool to a vet.
Around here we are able to send it by mail,
guess that would be possible over there in the states as well.
Just get some fresh stool, put it in some moist, clean cottonwool,
put it in a filmcannister and seal tight,
or put it in plastic bags a couple of times to prevent it from drying out.
When we send something by mail, it will be delivered the day after,
getting the results within a day or maybe 2.

When he won't poop, you might put him in some luke warm water,
keep him in there for about 10-15 minutes.
Get him out and put him in a container with only some white kitchen towel, a little moist ofcourse.
Most of the times they will start pooping not long after putting them in.

If he stays lethargic, a better idea then forcefeeding might be giving him some extra energy by soaking him in a saline/glucose solution.
This saline/glucose solution should be 0,9%.
You can make this by getting 1 L of warm water and put in 9 grams of Natriumchloride (just table salt is fine, as long as it doesn't contain iodine)
and 9 grams of glucose (or sugar if glucose isn't readily available).
Mix it in good, and let it settle to reach room temperature.
Put in you're frog for about 10-15 minutes.
You might do this in preparation of poop collection as well
