Issues after installing vBSEO Sitemap Generator

hi, i have some wird issue since install the site map.
my forum have two site maps (30k urls for one):
/forum/sitemap_forum_1.xml.gz‬ (work fine and mark with V at google wm tools)
/forum/sitemap_forum_2.xml.gz‬ (have an 404 error)

the first one (/forum/sitemap_forum_1.xml.gz‬) run great.
but i get error 404 on the sitemap_forum_2.xml.gz‬ on google wm tools.

i check at google webmaster tools, and its shows a worg file name:
sitemap_2.xml.gz, but the real name of the file is now: sitemap_forum_2.xml.gz.

i try do dell all the xml.gz file, but still... so i delete the sitemap_2.xml.gz from
google ms tools. and now i have there only one site map: /forum/sitemap_index.xml.gz‬
is that ok ?

You should only have the index submitted.
Clicking on the index should take you to the sub- sitemap files.

Hello,

You are seeing that error in G.W.T because you should follow this steps to get all of your sitemaps working:

* Login via FTP to your site
* Go to "vbseo_sitemap/data/" folder
* Move to another directory (or delete, if you want) all files inside it, *excluding* .htaccess and index.php files
* Regenerate your sitemaps
* As Brian mentioned, send to Google your sitemap_index.xml.gz URL (http.//yoursite.com/forum/sitemap_index.xml.gz)

Try to follow that steps and let me know how it goes.

Best regards.
