No there is not an any customization

The error you encountered is related to your environment/setup and not this theme. It's not possible to help you, if you don't want to provide in detail informations about your environment.

Hi ! Thx for great theme ))) I wonder is there any option to add meta tags in the topic header?

Topic pages should work as expected. You can add meta tags.

But where I have to add  it?

<meta property="og:image" content="http://ia.media-imdb.com/images/rock.jpg" />

something like this

I mean that <meta> is straightly deleted from header (header is created according instruction as a separate topic)

Oh, I understand. No, this is not possible with nopCommerce out of the box. You have to develop a custom solution.

No, sorry, this is far beyond to give some quick advice. Ask in the the nopCommerce community forum, you have a good chance, that someone has done this already and can be of help for you.

My  environment

Same error is :
