[Plugin: WordPress MU Domain Mapping] Cannot Comment on Mapped Domains

Seems like you filled in the IP address somewhere you weren’t supposed to. ??

Hmm, ok. I thought there was only one place it could go. On the Network Admin -> Settings -> Domain Mapping under Server IP Address, right?

Is there another place I should look?

I’m pretty sure commenting worked before. Also, I know it works on a separate, personal site, and I thought I had the same set up.

Thanks for your help.

There’s the spot where you actually map the domain to the site.

If you go to the SUB site and look under Tools -> Domain Mapping, there’s some options there.

Ok. I checked there and things look fine for some sites and for the example above, no domains show on the users mapping page even though I mapped them through Network Admin.

I actually turn the user domain page option off for our users and do the mapping manually.

It also happens on every mapped domain even though some are showing as mapped and others are not.

Any other thoughts? Thanks!

Actually, scratch that part about it not having the mapped domain on the users domain mapping page. I had the wrong site up. The rest still applies though.

How/why is the IP address being populated into the URL like that? Is that in the plugin file, or the sunrise file?

I have no idea why this has happened for the mapped domains. It used to work fine before.

Thanks for any help!

Is that in the plugin file, or the sunrise file?

Neither. There must be something in your virtual host configuration or somewhere else that is causing that. the plugin does a str_replace of your siteurl with the mapped domain.

Ah, after I read that, I decided to check the .htaccess file. We had double checked the VHOST info and all seemed to be right there, but we hadn’t checked the .htaccess file.

I found some code that I had used to try to prevent spam. After removing this code, the comments work again. (Yay!) I’m guessing the latest updates changed a few things and the code below was not updated for 3.1 or the domain mapping version 0.5.4, or it hasn’t worked at all since I added the code and no one told me.

# attempt to stop comment spam from non-referrer requests
RewriteEngine On
RewriteCond %{REQUEST_METHOD} POST
RewriteCond %{REQUEST_URI} .wp-comments-post\.php*
RewriteCond %{HTTP_REFERER} !.*nccumc.net.* [OR]
RewriteCond %{HTTP_USER_AGENT} ^$
RewriteRule (.*) ^https://%{REMOTE_ADDR}/$ [R=301,L]

Thank you both so much for your help! Sorry for the wild goose chase.
