Here's a weird problem I encountered. When I exported my database to my domain (I work on my theme locally on my computer), I had an error on my sitemap page which said something like: sitemap.xml.gz not found and my sitemap page wasn't displaying.
I changed the page's slug and reassigned it in the sitetree plugin and it worked. Does anyone know why? Did I forget to send a file or do something in particular when moving my site to its domain?
