So I have it resolved. I went Incognito and the page pulled up so then I added a plugin called Busted after I cleared my history (which I had already done before but didn’t have Busted in there). That made the page show up in the regular browser. I’m still baffled why it was only that one page. But oh well.
And the page actually will come up with the page id (/?page_id=656), but it’s blank. When it set it back to the post name, then the page redirects to the home pag.
Unfortunately not. I just happened to notice it on a demo I have set up. I’ve checked all functions, deactivated all plugins except BuddyPress, changed themes, and it happens with the default too. I switched the permalinks to default, saved, switched back. The /members slug will not work. No pages/posts in trash. But if I change it to even /members1 with a 1 after it, it works but the word “members” does not. I am just baffled.
