I’m starting to see a lot of HTTP Error 500 issues with a particular kind of wordpress sites, and I think the autoupdate to 5.0 that ran back in December is the culprit, but I’m not sure.
When folks have installed multiple instances of WP within the same directory
mysite.bergbuilds.domains (WP instance 1)
mysite.bergbuilds.domains/blog/ (WP instance 2)
the site that lives within the /blog/ directory now throws the HTTP 500 error. No access to /wp-admin/ either.
This has never been a recommended practice, and I’ve tried to help folks migrate to a subdomain when I’ve caught it. On the other hand, it generally still worked. Now, it doesn’t.
Is this likely fallout from the 5.0 update as I suspect, or am I being goofy about that? Has anyone else seen this issue? Most importantly, any suggestions for how I can correct this for ~ 20 sites here without losing peoples’ work?
