do i have to changes mo rewrite to yes in admin?.. it mentions about .htaccess... but i had nothing to with that...i did edit it with the able2know mod but not with this mod...
No more changes than overwriting the regular sitemap_forum.php with the one located in the contrib folder (which you have not done yet according to what I can see at your site).
The mod rewrite feature you are talking about in acp is only ment to rewrite your sitemaps url :
sitemap.php would thus be sitemaps.xml
sitemap.php?fid=xx would thus be forum-sitemap-XX.xml
sitemap.php?forum would thus be sitemap-forum.xml.
To do this, but it's not mandatory (just cosmetic type of feature
), you have to add the rewriterules provided in the contrib .htaccess in the .htaccess you ar using. Read the read me file and make sure tu properly ste path (should be the same as able2know's, if you install the fiel one level up, you'll have to put those rules in the .htaccess located at the root level and set path accordinaly).
Then, you should activate the feature in acp and test your sitemap
You could also resubmit your new sitemap : sitemaps.xml, but the old sitemap.php registration will still be working as is, providing rewrited sitemaps url.
