Hello! There are several headers and footers on any page, so i'm assuming, that somehow my master page template applies several times and i have no idea why.
As i understand, i'm using my master page template across the site plus ad-hoc templates with web-parts on it
Any ideas will be appreciated.
Check your page inheritance and what page templates are used on your pages. Find the page that contains multiple headers in your content tree and go parent by parent and check what page template it uses (Properties -> Template)
Thanks! I found that i set page nesting to all ancestors and it was root of all problems.
