Clean install with clean database, cleared up a few minor issues under Tools > Site health, but REST API still gives 404 Not Found error

After checking Tools > Site health, an optional PHP module is missing and the REST API gave a 404 error.

Weirdly though, I’ve lost the configuration lines in wp-config.php which enable multiple blogs (I REALLY don’t know how that happened). Going to tear the whole thing down and start from scratch again, I’ll repost an update (probably in a few days)

This is a clean WP install, the only plugin I have running is Akismet. All I’m doing is trying to create a new page on my blog

It’s been two months and I’m afraid I can’t remember how I fixed it. The only major change I made was moving from https on just wp-admin, registration and login pages to https on the whole site.

If the server hosting your blog isn’t the same one that normally sends email for your domain, you’ll probably need to edit your SPF file to show that the blog server is allowed to send email for the domain.

Your Web Host provider may have installed a firewall between you and the server.
Contact the admin of the server and ask if they allow outgoing communication on port 25,465,587.
It seems like they are blocking certain traffic. Ask them to open the ports.

Another update…

Tried disabling all plugins
Set selinux to disabled (was permissive so shouldn’t (and didn’t) make any difference)
Reinstalled WordPress from the Updates tab

Still no registration emails or logs to say why not

Ok, found a script to check if wp_mail was working, and it is, but still trying to register a new subscriber doesn’t send any emails and doesn’t generate any logs.

I’ve tried a few SMTP plugins but they can’t cope with my ‘main’ mail server’s security (cram-md5 login etc.)

Still baffled

The first link seems to concentrate on using external email services, I don’t want to do that since I have a working email setup already, it’s just the registration side that’s not sending emails and I’ve got no logs to tell me why.

If I can’t find a solution I’ll have to try a plugin, but that’s a last resort ??

I’m my own host, I run my own email server
