I do furniture repair work and have a couple of suggestions:
- Avoid the Gorilla Glue -- I see lots of failures and messes from foam out from it. A good PVA glue like Titebond or Elmer's would be my first choice. Remove the doors for ease of work. Inject glue with a syringe along the joint (known as a cope and stick), and not along the panel edge. Clamp and measure equal diagonals to ensure square.
- Wood expands and contracts minimally with changes in temperature, much more with changes in humidity. If it blew apart because of the raised panel expansion, I would expect it would be in higher humidity parts of year. The panel should be allowed to expand and contract (which is why raised panel rail and stile construction is used), you might remove the panels and plane off 1/8" or so from each edge (no reason to do the top and bottom because wood expands and contracts negligibly along that axis)
