Problem with warnings from Google

The fact is that it gives me an error in the google sitemap telling me problems with the priorities and asked whether this amendment would be fixed.

which puts

$ lastmod = gmdate ( 'ymd \ TH: i: s +00:00', $ lastmod);

$ vbseo_vars [ 'sitemap_content'] [] = array (
'url' => $ url,
'priority' => $ priority,
'lastmod' => $ lastmod,
'freq' => $ freq
);

and make change

$ lastmod = gmdate ( 'ymd \ TH: i: s +00:00', $ lastmod);


if ($ vbseo_stat [ 'urls_no'] == 0)
$ priority = min ($ priority +0.0001, 1.0);

If it does not please anyone and knows this is what agradeceria

there is a fix in here as well as a confirmation from google rep that it's simply a warning to notify you of the 'problem'
Google - Sitemap have the same priority

Thank you, I will see

greetings
