Two blogs but one has taken over

in your main domain database, check the wp-options table and check the blog URL..

also, refer this URL:

https://codex.www.ads-software.com/Changing_The_Site_URL

Thanks Ryans149, everythings working now.

Looks like I spoke too soon. If you open a new browser and load https://www.mydomain.com before you load subdomain.mydomain.com everything works fine.

If on the other hand you load subdomain.mydomain.com before https://www.mydomain.com the problem reappears.

Forcing a refresh (Ctrl + F5) doesn’t doing anything for it but closing the browser and starting over fixes the issue.

what in your .htaccess? (for both domains)

Hey Ryan, thanks for persevering with this one

I don’t have a .htaccess file as its running on IIS7

Also I started a seperate thread:
https://www.ads-software.com/support/topic/309135?replies=4

I wanted to start fresh with a clear description of the environment and problem details. I’m happy for your reply in whichever thread you like but I figure the information in the other thread might be of use.

Thanks again.
