Problem solved. It seems this was the error:

pawn Код:

if(isnull(inputtext3)) return Dialog_ShowCallback(pid3,using inline RegisterSafe2,DIALOG_STYLE_INPUT,"Saugi registracija","Įveskite atsakymą į klausimą","Tęsti","Išeiti"); 
                        if(strlen(inputtext3) > 100) return Dialog_ShowCallback(pid3,using inline RegisterSafe2,DIALOG_STYLE_INPUT,"Saugi registracija","{FF0000}Atsakymo negali sudaryti daugiau nei 100 simbolių\n{FFFFFF}Įveskite atsakymą į klausimą","Tęsti","Išeiti");

The code was in one line(for some reason) and as soon as I split it everything came back to normal.
