Thank you a loot!
Works great!

Best regards, Ira

Ok I will do it now. Thank you a lot one more time!

Thank you. I use main theme, no child. I disabled all plugins,deleted custom code, cleaned cache, and did all you have told but nothing happened. I still cannot update when I put block in Visual Composer in main blog page.

Maybe there is problem because I use this options within your theme: https://s24.postimg.org/fd319zp1x/image.png (I have to choose something) My main blog “Novosti” is set as static blog page.

When I go to Visual Composer I have to add block to filter categories. So, there isn’t same as your M10 (article display) so I use this https://s23.postimg.org/wymttca57/image.png

Then I can filter categories: https://s30.postimg.org/jrcweclip/image.jpg

But when I click on update https://s30.postimg.org/41i8cof9t/image.png all what I did is deleted and I get this:
https://s28.postimg.org/ckh317yal/image.jpg (like in the beginning).

In my “second blog” I don’t have this problems, probably because it’s not set as main blog.

However, if I cannot do anything I leave as it is. Thank you one more time for patient and great help!

Thank you. My blog is set as static page from the beginning: https://filetea.me/#n3wBwcuvYluRVi33baiGAXJXQ

I can edit main blog page in visual composer but all the time when I click on update page I lose everything.

I don’t know why. When I enter a “Novosti” page in VC writes: You have blank page. Start adding content or templates.
Than I create a block as I want and filter categories but when I click on update I lose everything. 🙁

But in second blog: http://laglika.gradskekarte.com/novosti/lag-lika-u-medijima/
I can edit everything in Visual composer without losing anything when I click update. Strange thing.

Maybe I should contact Visual composer support. I thought I was doing something wrong with theme settings …
Thank you a lot one more time!

Thank you a lot for a quick answer! I deleted category page and add one new static page with block filter.
Now it works: http://laglika.gradskekarte.com/novosti/lag-lika-u-medijima/
Great!

But in main blog page ( http://laglika.gradskekarte.com/novosti/ ) I cannot filter content by categories in visual composer. So, there I have now all posts and I want to have a posts with specific category.

Do I have to delete main blog page and open a another static page which will have function of a blog and then I can filter posts by categories? Or I can do it without opening a new static page?

Thanks a lot for a fast answer!
