Weird problems with GS3.2.0 and News Manager plugin

[D.O.]

THANKS Carlos, it's perfect!!!!
The patch "if (!@rename($oldfile,$newfile)) {" worked great!

But - at the same time - another old problem came out...

I typed a post with this letters "L'è" and when I tried to delete it GS allerted me with this message: "Error: incorrect path". After it, it was impossible to delete the post.

Into the folder named "posts" the file was written in this way: "l%E3%A8.xml". Then I tried to use your alternative "basic.php" for Latin language, but it didn't work. I hope it can be useful to fix these bugs.

Thanks again!
