Not able to delete downloads log

Hi,

When I am viewing the vbseo_sitemap (after logging in) and click the downloads log, I am unable to remove records. And when I try to I get this:


Warning: fwrite(): supplied argument is not a valid stream resource in [path]/vbseo_sitemap/index.php on line 259

Warning: fclose(): supplied argument is not a valid stream resource in [path]/vbseo_sitemap/index.php on line 260

Make sure your /data and /hits folders are chmod 777.
