Hello Catalin,

I did what you advised. Disabled every plugin (apart wp super cache) –> delete cache –> Activate tagDiv booster only (I don;t remember else boundle plugins) –> Delete cache again. So I left almost naked theme, but sidebars still don’t work.

Thank you for detailed instruction. I succeeded to set up sidebar at page using VC but unfortunately there is no result at categories. I set up everything properly (sidebar mode, custom sidbars etc.) at Newspaper theme panel. Please take a look at enclosed screens:

I also noticed problem with building widgets. Sometimes it can’t be saved and after adding elements and save they are “clear” without content.

I turn off plugins one by one (most important apart from some small extensions like icons pack) and deleted caches. Also with no result for displaying sidebar.
List o my plugins (additional): Cookie Notice, CodeStyling Localization, Collapse-O-Matic, Disqus Comment System, Mango Buttons, Login No Captcha reCAPTCHA, Pretty Link Lite, Reviewer, Scroll to Anchor, TablePress with extensions, Use Any Font, WP SVG Icons, Yoast SEO

I would be gratefull for other suggestions 🙂
