after login generate again the login popup

The popup on that page doesn't look to be the SCLogin module. When your on the first page, does the login popup (from SCLogin) look like the one in your image above? I'm assuming not.

I'm not sure what login popup that is, but you'd need to narrow that down and then contact the developer of that extension to determine why the popup is showing.

I hope that helps get you started, and sorry I don't have a definite answer on how to fix your issue.

Thanks,
Alex
