Joomla! Template LT Art Studio - Item Support

Dear template crew, I am preparing a multilangual site with your beautiful template for an artist friend. However, after 22 hours of struggling I have to give up because I cannot get the menus from the Dutch and Indonesian version working properly (home and articles in About Hetty Ansing). Would you please be so kind to take a short look and put me back on the right trail again. Site name: Ansing, login: admin - pw: hetty&jan, kind regards Leo
Hello LTHEME, this is a bit too easy kind of support and disappointing. I use Joomla 3 multilangual system and suspect the template to have a problem with the helix module, which I cannot solve myself. It is not possible to add submenu's to a menuroot item in an addes language and to HOME button does not appear in the mainmenu.
I am not familiar with Falang and do not want to loose all translation work done until now. How can I get support for my problem? Thanks very much in advance for your reply.

I have updated Joomla from 3.6.5 to the newest version 3.8.3. Update caused an error and now I can not login to the admin panel.

I thought. that it could be a problem with Helix Framework and found this topic:
where someone from Helix support recommends updating the framawork to the latest version. Maybe this will solve the problem.

Could you please help me fix this bug?
