Sever tests do not work

As I have already implemented all routines, the program can work well in my computer. But the results of severs tests show that the program could not pass the simple_load(pubic test) and other related daily tests. The error message remained to me there is a null pointer for reading documents, but why this function can work in my VM? Here is the message :slight_smile: :

(I implement the function of reading words from the document by fscanf and loop.)

Thanks!

Thank you very much!
