We have an error with the Yoast SEO Sitemap and some of the dates within our forum sitemap after an import. (running the latest of both plugins)
We thought we cleaned up all the redirected threads (topic) before importing from vBulletin but we had some redirects that were still in place, those redirects were imported; now the forum sitemap shows all of the redirects with the date of 1969-12-31.
When we go to the original redirect url thread (topic) we get: Access denied – you do not have permission to view this page , although we are viewing it as an admin, figuring we could just delete it.
We can do a 301 redirect, but that (i don’t think) will help us clean up the sitemap. As Goolge Webmaster Tools gives a An invalid date was found. Please fix the date or formatting before resubmitting.
Any suggestions?
