the bug was in the fill function.. i didn't checked if (x > m || y > n)
and after several tests, fill() counted some chars outside the map (map was not reinitialized each test case)

can't find out why i get WA... can someone help ?

#include <stdio.h>
#define isL(x) ((x) >= 'A' && (x) <= 'Z')
#define isBetter(p1,p2) (sol1[p1] > sol1[p2] || (sol1[p1] == sol1[p2] && sol2[p1] < sol2[p2]))
#define NMAX 55

int n, m;
char map[NMAX][NMAX];
char u[NMAX][NMAX];

int soln;
int sol1 ...
