Home page upstaging blog home page

This problem came up after I installed bbpress and made a few attempts at the integrations, which I didn’t have time to finish and I thought I’d set everything back to normal. I’ve checked my old wp-config.php against what’s currently up there, and they’re identical.

I’m hoping somebody can give me a quick tip on why all of a sudden I can no longer access my blog’s main page, the one controlled by the wp-content/theme/(themename)/index.php. Instead it re-directs to a page we’re using for our “home” page.

The url for the blog’s main page should be https://www.ourdomain.com/blog/index.php, shouldn’t it?
