Replace:

pawn Код:

hFile = fopen("Logs/chat.txt",io_append);
fwrite(hFile,entry);
fclose(hFile);

with:

pawn Код:

hFile = fopen("Logs/chat.txt",io_append);
if (hFile)
{
    fwrite(hFile,entry);
    fclose(hFile);
}

I already mentioned that it can crash the server in that thread. It's good to read the comments before using something!
