this site is not a blog of articles to submit or something like this ,,what is your advises??

2- the main problem is my sitemap
316 URLs submitted
1 URLs indexed

1 onnnnly indexed
why?,,is there is a main problem? or maybe my xml sitemap generator plugin setting are wrong
see :

or it is just a time and everything will be ok ?

It takes time for everything to get updated. It could take google months to index all of your pages. Of course you should still be building links to all the pages, as this will help speed up the indexing and help you get better rankings for each page.

months !!!
mm ok thanks,,but my setting is ok ?
