SQL error, now website won't load?

I was changing some sql on my website and accidentally made a syntax error. I was shown the error, and when I corrected it and tried to load the website again, it would not load. Doesn’t get to an error or anything, just shows “Waiting for [site].000webbhostapp.com” in the bottom-left url info.
I suppose it may or may not be related to the sql error.
Is there some way to “reset” the website?

EDIT: Problem resolved itself after some time
