Greetings for all members. Excuse me for my bad english.
I got next problem: modules don't displays.
Example: I create a standart navigation module (breadcrumbs) (from case). Checked, that it works in another themes (templates). But in sj_appstore_hitech it doesn't works. Used region: Breadcrumbs (also tried User1, debug, header1)...
Also I got the question - if there are no modules about the region, when I selecting output region for modules, it means that this region is available in all templates on my site?
Thanks.

UPD: with region "debug" breadcrumbs works. but when I tried change this (region) to "breadcrumb", breadcrumbs dissappeared. I checked, in details.xml region "breadcrumb" is present.

hah... lol. Guys, problem solved. field for breadcrumbs is initiated in templateDetails.xml, but not implementated in layout. To solve this problem I added in needed layout region. In my situation - layout file was: templates/sj_appstore_hitech/layouts/sj_appstore.xml
And position (region) was added by next code: <position height="" width="" style="xhtml" type="modules">breadcrumb</position>
WARNING: <position></position> tag must be wrapped by tags <positions></positions>
