Yoast XML sitemap not working

Hi
Just wondering if you managed to solve this? My sitemap is working fine, date wise etc, but in Google Webmaster it is still showing as pending and has been for a number of weeks. I have again today tested the sitemap in webmaster tools and it shows as all ok-
Sitemap: /sitemap_index.xml
Type: Sitemap index
Number of children in this Sitemap index 6
Error details: No errors found.
However the first page still shows pending and on the dashboard it states no URL’s submitted.
I’m wondering if I should revert back to the Google sitemap plugin however when I used that previously it didnt seem to index my event categories.

Hi,
I have the same date issue, where 1970-01-01 00:00 is shown on some (not all) ‘child site maps’ of sitemap_index.xml. Any idea why this happens? Or is this irrelevant? At least to me it doesn’t seem as if dates should look like that.

Still no, I contact to Yoast via contact form but they are not responding and also not giving me support for this free plugin.

I want to know are you using Genesis Framework ?

Have you tried these solutions?

@esmi: I am sorry, I thought it might be a good idea to add my issue here to this already existing thread rather than opening a new one with the identical question.
