I was adding a blog post, I clicked on publish/save and a white page appeared that said 404 internal error contact your admin person. I’m the admin person. I checked with my host provider (In motion hosting) they said it is the theme. They tried to install sydney and sydney child at their end and they only got blank pages. Under all pages my pages are still there but there is no visible website to view. What’s going on??? My beautiful website that was almost complete is gone. Hopefully, the backup will work. In the meantime can anyone explain what the 404 internal error is and how to avoid it?
