I get this error from google regarding the sitemap:

All the URLs in your Sitemap have the same priority.
All the URLs in your Sitemap are set to the same priority (not the default priority). Priority indicates the importance of a particular URL relative to other URLs on your site, and doesn't impact your site's performance in search results. If all URLs have the same priority, Google can't tell which are more important.

Is there a way to resolve this issue?

We've covered the sitemap module a number of times recently on other threads. The module is unsupported and was developed by an outsider who hasn't kept up the code. We recommend disabling it until a new version is developed by either the Pligg devs or someone else.

This is what John Mueller
Webmaster Trends Analyst at Google Zurich had to say about the warning.


Hi everyone!
I just wanted to give some more information about this warning
message. It does not mean that there is anything wrong with your site
or your Sitemap file. Since "priority is relative within your site, by
using the same priority value across all URLs you're effectively not
telling us anything at all. Theoretically, it would be cleaner to just
not include any priority values in your Sitemap file, if you can't
provide relevant information with that number (personally, I would try
to do that).

So in a sense, it's just giving you a heads-up that you could be
providing something of value through that field instead of just having
us ignore it altogether. It's up to you & by leaving the same
number for all URLs or by removing the tags altogether you certainly
won't cause your site any "harm."
Hope it helps!
John

The sitemap works so there is no reason to disable it.
