Horizontal Menu Module Doesn't Display On Homepage

[Kozlo]

Hi, 

I worked on my website on categories and all of sudden the horizontal menu stopped showing on my homepage. It displays on CMS pages and on pages from the catalog. 

I tried to restore last modifications I made but the problem is still there. I checked positions of the module and everything is looking good. Does anyone have some suggestions about what are causing that odd problem?

 

p.s. if I go to Theme and start the live preview the menu shows on homepage.

 

I can't provide the url here, but if you want to check it out pm and I'll provide you credentials and url to check.

 

Regards,

Aleksander
