Yes I know that already. I used "XML Sitemap" on some sites. The problem is when using "XML Sitemap", I have a few sites that gives this error:
Error loading stylesheet: A network error occurred loading an XSLT stylesheet:
http:// www.mydomain.com/wp-content/plugins/google-xml-sitemaps-with-qtranslate-support/sitemap.xs
When searching for answers, people on the wordpress forum had the same problem. The developer of "XML Sitemap", said that's because we had the "XML qt" plugin installed at some point and to delete the files. Well I don't have the plugin and I deleted all XML files and re-install and I'm facing the same problem.
When using Yoast, it comes with XML sitemap and it looks like this, "sitemap_index.xml". I did not want to pile on more plugins to the sites. I eventually had to disable the XML function in YOAST on some sites and install "XML Sitemap" anyway. However a few sites are giving me the errors so I tried other sitemaps which worked well on the sites. However the software refused to extract the "sitemapindex.xml".
Anyway I can't keep on messing with different XML maps which keeps on pinging google to raise suspicion just to make this program work. Besides in the W2 video they mention that it can be any sitemap name.
