Hi,
Like the title says ” domain mappng is forcing https on subsite”. what’s happening is that when you login to the mapped domain, and for instance you try to add a new page/post etc.. when click on the Add New button, users being redirected to the https of the site.
When i deactivated domain mapping it works, which means that the problem is happening because of the domain mapping plugin.
I also want you to know that i’ve already clear all cache and turn off all caching mechanism.
Thanks in advanced for you reply and help through fixing this issue.
