Joomla! Template LT News - Item Support

Where is the How To section? Where I could find some information about Template Module Positions or Modules Configuration?
Comment in status pending...

It will be published after it has been approved by the Website Administrator.
When I entering extensions - modules - Home slider JO K2 - i only see title and image of the slider. nothing i can do... there is no option to manage that slider... I thought that there is some kind of mistake, so i delete whole website from the server and run akeeba kickstareter...
But now i have the same problem - only title and image...
I have a problem with comment module because I can not turn off avatar display and I can not see the content of the comment. There is the date of the addition, the name of the author, but you can not see the content.

See link to the article below:
https://www.e-mosina.pl/aktualnosci/kultura-i-rozrywka/item/99-miedzynarodowy-festiwal-chorow-uniwersyteckich

Is there any possibility to change the configuration fo the comment or I should change the code at modules/mod_k2_comments/tmpl?

And what about content of the comment?
Is it possible to add ads using the simple form in LT news template? I would like to allow guests from the front-end (without logging in) to provide the title, content and photo. Something like a comment module. The advertisement would be automatically added to the appropriate K2 category. Advertisements would be displayed by using the item overview in a given category as the other items in k2 are displayed on the main page.
Alternatively, the superuser would have to publish the advertisement - like the comments module.
where i could customize coming soon page and error page? I still have lt news logo on them... ant those pages have wrong colors... (i am using preset 4 as default )
