If you’re still looking, it’s in /wp-content/plugins/revslider/inc_php/framework/
I’m not sure entirely what you mean.
Basically I just want to redirect after login to something other than the admin panel. It seems like the best way to do this is to use the filter that’s already in place. Problem is, that only appends the page to the site’s home URL. I want to redirect to an entirely different multisite altogether.
I’m not positive how preg_match() would help me. Doesn’t that just check for a string and return a logic value?
