New Posts Not Showing Up

Yesterday I was uploading old text posts that I had written, and everything was showing up fine, but now the last four text posts I have written aren’t showing up.

I’ve tried changing my theme and it hasn’t fixed anything.

If I post from the app on my iPhone, the post shows up, which is weird. I want to post from my computer, though.
