Image upload problems for multisite subdomain site

(Network Admin / Sites / Settings)
Siteurl: https://www.site1.com
Upload path: wp-content/blogs.dir/2/files
Fileupload url: https://www.site1.com/files (I also tried site1.mainsite.com and didn’t work)

That’s wrong… Your fileupload URL should still show as site1.mainsite.com/files (yes, I know it’s weird, but that’s how domain mapping works).

What domain mapping plugin are you using?

Did you verify that allowoverride is set to all on your httpd.conf?

I’m using WordPress MU Domain Mapping plugin.

Allowoverride is set to all.

I’m also looked at blogs.dir folder ownership (chown) set. its user and group are same.

What am I missing?

Did you check to make sure that uploads worked before you mapped the domain?

Yes I did. Currently, uploads are working on unmapped mainsite.

At first, I set the my main site address as mainsite.com instead www.mainsite.com. At that time uploads were not working. And later, I changed it to www.mainsite.com (manually search and replace in database). Still didn’t work. Could that be a problem?

Thanks for trying to help me Ipstenu.

It’s okay ?? You’re doing fine!

Are you trying to map the main site on your domain? You can’t do that.

You can map the subsites only.

No I’m not trying to map the main site. (or am I? Here is the screenshot of my network sites section: https://i48.tinypic.com/29as192.png)

There is no problem at the main site.

I mapped the subsites only as you say. My uploads at the subsites are not properly working. When I look at the uploaded image path, it’s showing

https://www.site1.com/files/2012/06/image.jpg (which is broken)

I also look at the blogs.dir folder, I see the uploaded image there:

/blogs.dir/2/files/2012/06/image.jpg

Apparently the image is successfully uploading into the blogs.dir folder. That’s fine. But I can’t see the image on the subsite.

I’m exhausted now ??
Thanks for helping again.

Look on the far left of that screenshot. See how it says / ? That isn’t right ??

Are you using subfolders for your subsites? Because if you use subdomaains (i.e subdomain.domain.com ) for your sites, then that view is wrong, and so is your .htaccess ??

I’m confused. I don’t use sub-directories, I used sub-domains at first install. But, when I look “Settings – Network Setup” section I see the setup codes like this ss: https://i49.tinypic.com/pq5hw.png

on that screenshot, htaccess codes are for sub-directories. am I wrong? But I checked sub-domains at first install.

I tried that htaccess codes though, didn’t work too.

You said that view is wrong, what do you mean that? How should be that for right view?

Sites should look like this: https://cl.ly/21152C1Z2Z2U171l2K46

See how I have one with / and the rest have the name of the subfolder? That’s what’s wrong. EVEN when you map a domain, that stays true!

Did you edit those sites manually instead of using a plugin?

Yes I did edit manually, because when I add a new site it looks that: https://site5.mainsite.com in sites/info – domain field

which It’s not open in this way. So I edit that field as https://www.site5.com
Than site5.com is opening.

because when I add a new site it looks that: https://site5.mainsite.com in sites/info – domain field

You’ve done something very wrong.

The domain column should have the orginal name of your subsite. So if you named the site site5.mainsite.com, then ‘site5’ shows up in domain.

The Mapping column should have the domain name site5.com

You should NEVER EVER have to edit the sites manually. Otherwise what’s the point of the plugin. You mapped things ‘wrong’ and I don’t know how.

If I don’t edit manually, the subsites are not opening. I guess I’ve done something very wrong as you said. But what or where?

In wp-config, I set the domain_current_site as www.mainsite.com
Otherwise the main site is opening without www part. I dont want that. So do you think that adding www part be a problem?

Another curios: https://i49.tinypic.com/w8ox9s.png
Server IP address is empty in domain mapping configration page. Should be entered my mainsite ip address?

And last, what do you suggest, should I delete all and return single installation and then start new multisite configration again? (I already have 4 subsite with content by the way)
Or should I contunie in this way? (because the subsites are working except image uploads)

Addition, these both are not opening:

site5.mainsite.com/wp-admin
https://www.mainsite.com/site5/wp-admin

only when I manually edit site as https://www.site5.com
then working https://www.site5.com/wp-admin

I don’t know what’s wrong.
Hope you help me Mika

https://i49.tinypic.com/w8ox9s.png is the wrong page.

That’s the page where you add domains, not the domain listing. See on the menu on the left it has ‘Domains’ below? Click that.

Was any of this working before you started mapping domains?
