vbuploadXXX tmp files in forum root directory
 

Hi,

I just updated to 3.8 and I get files like this in our forum root:
-rw------- 1 apache apache 0 Apr 21 07:26 vbupload9r0HwG
-rw------- 1 apache apache 0 Apr 21 07:38 vbuploadkhUgaL
-rw------- 1 apache apache 0 Apr 21 07:38 vbuploadcqGnPJ

What should I do to disable/fix that?
