Yes that is correct. Make sure and back everything up fist in case you delete the wrong thing by mistake. But I’m not sure if that’s going to make a difference to whatever the real issue is, because the prettyPhoto code/file does not show up at all unless you use a template, or if there is custom code somewhere linked to it. 16gb of errors is still extreme and unheard of, I still doubt that this theme is the cause. Hostgator is known for getting things wrong and blaming WordPress for their own server issues (I’ve had them a few years ago)
I’ve never seen that happen out of all the people I’ve helped here. I have a lot of clients that use some of Appfinite and StudioPress themes and this has never occurred. I’m not even sure how that could even happen from an error. If this continues after you delete those files, and you know that the prettyPhoto is not the cause of the problem, then it’s probably time to find a more reliable host IMO.
Let me know what happens when you get a chance.
