pawn Код:

format(zin,sizeof(zin),"{66ff33}Adminas {66ff33}%s: {66ff33}%s",vardas,isnull(params));

Should be:

pawn Код:

format(zin,sizeof(zin),"{66ff33}Adminas {66ff33}%s: {66ff33}%s",vardas,params);

Also NEVER use 256 byte long strings!!!!!!!!!
Chat strings can only be maximal 128 bytes, you are wasting twice as much memory as actually needed.
