Subsite's administration redirects to main site's administration

Found the problem.

I was using the same DB for both the main site and the subdomain.
Once I created a seperate DB for the subdomain everything worked properly.

That’s … not multisite.

Multisite you totally can run on the same DB. What you did was make a second install, and your host is a bit daft for suggesting that without bothering to read the multisite directions.

OK.
Before I asked the host’s people I followed the “Create a Network” instructions myself.
When I didn’t put another wordpress installation in the directory for the subdomain site than I got a server error when opening the site.
So what’s the path to solving this if not putting another installation?

BTW, now that I have a second WP installation and a second DB everything seems to be working fine.
I have the subdomain site in the site list under network management.

But I’d still love to hear your solution…

OK, it’s not “I’d love to hear your solution” anymore.

I understand now that the way I made it work is incorrect.

Can you explain how do I create a subdomain site under the same WP installation and DB?

When I didn’t put another wordpress installation in the directory for the subdomain site than I got a server error when opening the site.

Well without seeing the error you got for wildcard subdomains, my best guess is you didn’t actually set them up correctly.

On the host’s side I added in cPanel->subdomains ‘*’ (as a wildcard) and the specific subdomain name.

See that’s not right ?? * is a fine name, sure, but where did it point to? It should point to /public_html/ (which is where you should have installed WP).

I really appreciate the help.

In cPanel->subdomains where I added * it automatically added this: Document Root: /public_html/wildcard.

Also, I added the name of the subdomain itself, for example “biz”, so in cPanel->subdomains what was added was /public_html/biz.

I did install the main site under public_html.
After setting up the network, I created a new site from the administration panel and WordPress automatically created the dir “biz” under public_html, and in this dir I put the second WP installation.

I can repeat the process and let you know what was the exact error message.

In cPanel->subdomains where I added * it automatically added this: Document Root: /public_html/wildcard.

Right. That’s the problem. /public_html/wildcard

That should be /public_html/

Nothing else.

Amazing.

Worked like a charm.
I wonder why they’d make the “wildcard” addition automatic.

Anyway, I planned on fighting this issue all night long and you solved it in a sec.
Thank you so much.

Glad to help ??

I do wonder why on earth any host makes the wildcard addition. *tsk* Silly hosts.
