Certain custom permalinks with enabled root profiles results in a blank page

[henrywright]

When I use the following custom permalink settings

/%author%/%post_id%/

and enable root profiles

define ( 'BP_ENABLE_ROOT_PROFILES', true );

I find that when visiting a blog post even though the URL will read something like example.com/username/615, I get a blank page with "Members" as the page title.

Just to add, by blank page I don't mean a white page of death - I mean I get a page styled properly BUT instead of getting the post content displayed, all I get is "Members" as the page title and "Members" as the page heading.

Thanks for reporting this, henrywright. I'm not surprised to hear it's an issue.

I have a feeling that this is going to become moot once BP has adopted true rewrite rules (though I'm not totally sure how we'll resolve issues with BP_ENABLE_ROOT_PROFILES). I'm assigning this to johnjamesjacoby for more advice.

Rewrite rules should take care of this completely. Author archives are special cased in WordPress, so I'm anticipating some amount of complications. There is little we can do about this now unfortunately. We could check the default permalink structure, and try to dance around conflicts in cases like this, but different permutations will quickly rabbit hole us into circumventing something that we have plans to correctly fix.

I'm going to close this as a duplicate of #4954, knowing it will be addressed once rewrite rules are playing nicely.
