Hello.
When submitting my sitemap to Google I had issues (404), and eventually noted that the .XML files were not set to permission "644" by default, but rather "600".
I was able to resolve the problem by manually changing the permissions to "644" in FTP, but that necessitates doing so every time I generate a sitemap through ZP admin tools.
So, just reporting that (bug?) and would like to know if anyone could suggest a bit of code to tweak in the plugin to generate "644" permissioned files instead of "600" on sitemap generation.
