Any progress on this. I too am looking to redirect
domain.com/page/?var1=A
to
landing.domain.com/?campaign=x&var1=A
I tried a regex redirecting
domain.com/page/?*
to
landing.domain.com/?campaign=x&*
but instead that redirected to:
landing.domain.com/?campaign=x/?var1=A
Bob,
I was able to fix the issue on my site, and yes, it was a plugin conflict issue.
The problem went away after I disabled a plugin called “Quick Empty Trash”.
I’m not even sure what it did. I think my assistant installed it for some reason. Anyway … it’s gone and the problem is gone.
Hope this helps you.
Simon
Did you fix? I’m having the same problem.
