Is there a setting that forces HTTPS on administrator?

Is there anything in JFBConnect that forces HTTPS on the administrator section? Like a plugin, an option, configuration setting, etc...?

I'm moving hosts & have my site temporarily installed on a different domain. I can see the admin section login form, but as soon as I click "log in" I get redirected to https://.... which spits out an SSL error since this temporary domain I'm using doesn't have SSL. I'm trying to find what's forcing SSL.

Through Googling I've found 2 main areas where SSL is normally forced (Global Config & Admin Tools) - I've made sure both are turned off.
I've verified the following options:
Site > Global Configuration > Server > Force SSL: None
Components > Admin Tools > .htaccess maker >
Force HTTPS for these URLs: (Blank)
HSTS Header: No

I've also checked the .htaccess in the root & root/administrator.

I've asked SiteGround techs. They say there's a plugin forcing the SSL redirect. Do you know of any of your plugins, modules, components, etc I should check?

I'm on Joomla 2.5.27
JFBConnect 6.1.1
SCLogin

Is there anything in your programs that could force HTTPS on the admin section?

Thanks for your help,
