Help with vBSEO Sitemap install...

I followed the install instructions, but am having trouble with getting everything to submit to Google.

I tried to manually generate a sitemap, but fell short:

homepage] [1s (+1)]
[SECTION START] forumdisplay [1s (+0)]
[forumdisplay] forum_id: 3, total threads: 0, pages: 1 [1s (+0)]
[forumdisplay] forum_id: 7, total threads: 42527, pages: 1702 [1s (+0)]

... and so on.

Is there something that I'm doing wrong?

Did you do the following step:

1. CHMOD 777 the 'vB-root/vbseo_sitemap/data/' folder
