Many people complain about an error 404 when calling the sitemap page but did not give reproducable error descriptions. I could reproduce the following error behaviour of the plugin:
- Sitemap gives a 404 after disabling and reenablng the SEO plugin. Seems to be a general behaviour.
- After that I disabled the sitemap functionality "XML-Sitemap" and reenabled it. This brings the sitemap back again.
- Tested with current version of W3TC v0.9.2.8 active, but deleted page cache after reenabling the SEO plugin.
