No login from the frontend SCLogin module

Bury,
Apologies for the delayed response. I just went to your site but couldn't find the SCLogin module. Can you enable it on some interior or test page and let us know where we can find it to test?

Can you also explain this a bit more:

but I can't start/open user session with this module in the frontend.

Do you get an error, or does the page just refresh without being logged in? Can you try disabling caching in Joomla and see if that fixes the issue?

Thanks,
Alex
