Login Trouble at FrontEnd

Hi,
I have login Trouble at League News template.
Standart login lodule don't work - after entering credentials it swith to main page without login.
I install and try GK_Register - but it only register option - not login.
And it work only afte that i update module from this post https://www.gavick.com/forums/league-ne ... gin#p83283

Is your template up-to-date ? Please publish on some position default login module and check whether it is working. If no please make another test with default template like 'Beez' this give us more details about your case and allows to find the source of problem.

It's very strange but trouble in my database.
I copied data to test db and swith site to it - trouble is gone.

Maybe this helpfull for something.

Surely it will be valuable solution for other member, thanks for posting.
