George is right. I have a miniature biscuit joiner that uses biscuits down to 1/2" and it would not be a solution for this problem. The issue at hand is the joinery of the cabinet itself. The small area of the end grain joint provides little or no strength. It would not have lasted long at all. Given the small dimensions of the stiles, they must be let into the base and top pieces to provide structural strength. I would have done a half lap sort of join between the uprights and the base. That would provide a long grain to long grain glue joint. What I see is like a table with the legs butt glued to the underside of the top. Sorry, but I see no way to fix this problem. Dowels or tenons might do it, but getting things aligned after the fact will be tough. I would start over with a proper design.
I've gone out to find myself. If I return before I get back, have me wait for me.
