New warning - supplied argument not valid

[mcl]

I've got some quirky stuff going on, in that I'm seeing a new warning (displaying in my browser window) that I don't recall seeing. I can't figure out if the warning was always there and I never noticed it (not likely), if my hosting service turned on warnings without my knowledge, of if something broke.

Anyway, here's what's happening:

I wrote a script that (among other things) opens a file, writes to that file, and closes that file. The script has worked, and still works, thus my questions revloves around why I'm seeing these warning messages:

Warning: fputs(): supplied argument is not a valid stream resource in c:\websites\celebarrus278\mysite.com\updaterates.php on line 796

Warning: fclose(): supplied argument is not a valid stream resource in c:\websites\celebarrus278\mysite.com\updaterates.php on line 797

Thank you - Mark

Could we see the code?

I think I found the problem ... I write to both a file on the hosting server, and on a backup server ... the backup server was down thus the code couldn't locate where to write the second copy.
