I am a pastor of a new church plant in Japan and I just started our first website. This is the first time I've messed with any kind of website! I bought a domain name, got WordPress, downloaded a nice theme and got the page set up. However, whenever someone tries to access my page for the first time, they type in the address (www.mitakafamicen.com) and it takes them to some bland sitemap-ish looking screen with mostly just bland links from my homepage. If you click on any of the links, then it takes you to the 'real' page. Why does it go to the empty site first? How can I fix it?
Secondly, it might be unrelated, but every time I try to view the page, I always get an SSL error, or a message saying 'Some contents are not secure. Load page anyway?' The https is red. I called my server company, a Japanese company called Leo Server, and they told me that there was nothing I could do about it since I was using my own domain name and I would need branch my website directly off of their sites to get a green https, but that it would change my URL to include some of their stuff (sorry, not familiar with internet terms).
Is there any other way I can make my site secure so that I don't have warnings and red https symbols anymore?
