When im trying to set layout option 'left-main.xml' from admin panel as default, its loading something like 'full.xml'
You can see the result on the site: geo-vologda.ru/

With YT Framework this position is all right, but i want to set it as default.

Dear Dmitry111!
When you use layout: left-main.xml, you must configure(in admin) the value as:
Main width:650
Left width:310
Right width:0
You can use cpanel(click select radio of layout) to try, then configure the values ​​in as administrator cpanel
